But wait, there's a boring privacy message!

Don't you just love the word annihilate? It sounds so ominous. I like that it gets used in physics, and that the way it is used in physics is as crazy as it sounds. In physics, it refers to the fact that when matter and antimatter meet, they literally turn into energy. Literally in the literal sense. And it becomes a surprising amount of energy. One milligram of antimatter combined with regular matter would release enough energy to send a space probe to Pluto and back, or power a car for 100,000 years, or, if you don't contain it, cause an explosion similar to a nuclear bomb, and about the same size as the ones that have been used as weapons.
Anyway, in this case the annihilation is not really very frightening, unless you are trying to get a 2048 tile and you have a 1024 tile near a -1024 tile, because with this new setting turned on, they could merge and disappear. (But no energy is produced, unless you count the energy released into your forehead when you hit it with your hand.)
That's right, in Adjustable 2048, there is a new setting called "Negatives Annihilate". Any negative number will merge with its equivalent positive number, become zero, and then vanish. The ability to make negative numbers spawn has existed all along, but they weren't doing much except making it even more difficult to keep your board from locking up, unless you were playing with only negative numbers, in which case it would have been just like a positive game, but with a different color scheme.
Incidentally, the negative color scheme is actually the negative of the regular color scheme. The red, green, and blue levels are "reversed", as in, a lot of red and a little green with no blue becomes a little red and a lot of green with maximum blue.
Anyway, if you turn on Negatives Annihilate and add -2 and -4 to the spawn tiles with probabilities that are the same as the regular game, what you get is sort of the opposite of a normal game. That is, it's still hard to get a 2048 (possibly harder), but the difficulty is no longer in keeping the board from filling up, but in keeping any given tile on the board at all. In fact, one challenge you can try out is to just fill up the board. It's not very easy.
I hope to soon make it so that you can save your settings for Adjustable 2048 and share them, just like you would Custom Themes. It's sometimes surprising how different the game can be just by combining settings in a new way.

It has come to our attention that a lot of the custom themes are just interesting stylings of the numbers, which leads one to ask: Why have the numbers also appear in the corner? In support of this phenomenon, you can now turn the number labels off for your custom theme. Now your numbers will appear alone, in their full glory!
But also I've wanted to add that setting for a while. It's actually the way I prefer to play most themes, and it has always been available for the player to set it, but, aside from our own Birthday Cake theme, it is always turned on by default.
Why you ask? Well, let me tell you a story. Back in the early days of 2048, probably before you were born (no really, it might have been), when (to my knowledge) the first "Build Your Own 2048" was launched at usvsth3m.com (don't go looking for it they took it down a long time ago), my memory is that it had no little captions telling you what number a tile was. You had to just remember. Which was part of the fun. But then these darn newfangled sites came along and decided to put the little labels in the corner. I didn't like it, but then again on some themes there was no clear order to the tiles and it took a lot of the meditative aspect away from the game when you had to puzzle over whether you're going to screw up your game by thinking you're about to make one tile when really you're about to make another one.
So, by the time this site got going in earnest, back in January or December, it seemed to be the expectation that there would be number labels, so I reluctantly put them in.
But some custom themes are created with the intention of the user being confused and entertained by other numbers and letters that show up as a substitution for the numbers, and I'm all about creating weird (but tasteful) confusing things. This setting is especially useful if you want to be incredibly annoying/hilarious and make tiles that are all indistinguishable, or have the normal numbers but in the wrong order.
In addition to those things, I have a particular love for themes where the images have a logical order. For example, our Solar System theme, where you start at the center of the solar system – the Sun – and work your way outwards, through Mercury, Venus, Earth, Mars, Ceres (yup, Ceres), Jupiter, Saturn, Uranus (stop giggling, that's childish), Neptune, and Pluto. (It actually contains more things after Pluto, but, I digress.) I think ordered themes are better to play without the number labels, because it's fun to remember what order these things are in, and could theoretically even teach you something. And odds are probably about 50/50 that you're actually supposed to be learning something RIGHT NOW.
Seriously. 2048 is not a good substitute for school. If history class is boring just imagine what kind of meme a given historical event could fit into. I want a 5 page essay on that by tomorrow.
Wait, I forgot what I was talking about. Oh yeah, the Build Your Own 2048 "Show numbers" setting. That's a thing now. Have fun. But not too much fun, and, if you happen to be a student, not in the middle of class unless it involves learning what you're supposed to learn in class.

While making the instructions more readable on mobile devices, I stumbled upon something. The reason they were tiny on phone screens was because the whole page was just getting scaled tinier, and the fractal explorer didn't even know it, so it was using the wrong resolution for high resolution displays (anything referred to as "retina" and basically every phone).
To be more specific, it was using a much lower resolution on my MacBook Pro (and probably every laptop with a similar display), and a resolution on my phone that was at least a little bit lower, and possibly A LOT lower. For the laptop it was probably operating at about half the actual resolution, which means the pixels were twice as big as they needed to be. On the phone...it's hard to tell.
Like a lot of phones, my phone's display has such tiny pixels that I can't even tell when it's displaying a checkboard pattern where the squares are one pixel wide. It just looks like a solid color. And with high resolution displays, writing a web app that figures out the resolution is not much better than squinting at the screen, because ... well, it's a long and arduous story, which I'm not going to try to explain right now.
It suffices to say that if you use the fractal explorer with a mid-range phone screen made any time after 2015 or so (in my case a Nexus 6), you might have to wait a while for the view to sufficiently render - depending on the area you're looking at and how sharp you want it to be, anywhere from 1 to 10 minutes - but it's worth the wait. Usually when I make an improvement to something on my website and get really excited about how great it looks, I show it to my wife and she says, "I think I see what you're talking about." This time I showed her a view of a fractal on my phone and her eyes went wide, and she said, "WHOA! That's so sharp!"
So, yeah, it is now REALLY REALLY REALLY sharp on phones. Like, it's scary.
It's also really sharp on high resolution laptop displays, which is more cool in terms of the fact that you can see it better and see a wider area because the screen is bigger. But the sharpness is really ****ing insane on a phone. Yeah, I said "****ing".
Also, the instructions are now much easier to read on the phone too, so there's that.

The Fractal Explorer is pretty slow on phones, but a lot of views are still tolerable especially since it uses incremental levels of iteration (without ever having an actual iteration limit) and calculates a sparse grid of points before filling in everything. And it turns out that a lot of visitors are using phones. But up until now you could only re-center a view on the phone, never zooming in or out. Now you can do that with "pinch" gesture and "spread" gesture (the opposite of a pinch). You can also move with swipes in addition to re-centering with a tap (which can be awkward at times).
Unfortunately, it is quite slow to respond to gestures (at least on my phone). I haven't tested this on other phones or any tablets, so I can't guarantee that the gestures work, but they are likely to work, because I based them on the same methods that I use for 2048. So you might just have to be patient. One pinch or spread changes the zoom by a factor of 2, and it probably will work, it just might take 5 seconds to react. There is also some chance that it will perform a "fake" zoom, similar to what happens on pages like this one when you want to magnify the text. In this case you'll end up magnifying the pixels instead of seeing more detail in the Mandelbrot. This came up in testing, but only if I moved my fingers very fast, so don't do that.
I am likely to be working on making it respond faster today or tomorrow, so be sure to check back soon.

As can be seen in the new instructions, the Fractal Explorer now has two palettes (color schemes) which can be toggled with the "P" key. The palettes look similar at first, but quickly become different as you zoom in. Usually one of the two palettes looks better than the other. Initally the original palette shows. The second palette is much better for areas where there is a lot of "noise" because a there are many different colors right next to each other. It cycles mostly with one color (green) for a while, which means the noise at least looks green, but then as it goes on it develops a blue tinge, which cycles on a much deeper scale, and ultimately it cycles red very, very slowly. It takes a phenomenal 312,500 iterations for a full cycle (red going back up and then all the way back down as part of the mix of colors), which really shows off the unlimited iterations of this fractal viewer, as it is possible to see situations where the red dominates.
In addition to the extra palette, you can now click with the left mouse button to center the view to your click. This is especially useful when you want to zoom into a particular spot and the keyboard doesn't give you enough control for it.

As most fractal enthusiasts are aware, if you zoom in far enough on a fractal, you reach a limit as to how accurately computers can store a normal decimal (technically floating point) number. At this point you have something like 2.1234123412341234 and you add something like 0.000000000001 to it, and you get the same number again, sort of like running out of space on a piece of paper when you're writing down digits and deciding that it's better to just give up on the addition. If your computer tries to store extra digits on another piece of paper (to continue the metaphor), it becomes much, much slower, because the processor is constructed to handle the, um, smaller pieces of paper.
Usually what happens is that the fractal image starts to have big rectangles of colors rather than more details (like pixels, but sometimes not square). For my fractal explorer it was doing this weird ghostlike overlay of multiple distorted views of the fractal. This looks kind of crummy, so I fixed it to do the rectangles.
You can now login using Facebook. Currently, the login only relates to creating custom 2048 themes (where you choose the images on the tiles), because you are required to have a login to do that. To prevent people from doing stupid things.

Some months ago I said, "One thing I'm not going to do is make something for people to add their own images to 2048 tiles. That would be asking for trouble." Today I'm proving myself wrong. I did, however, make it so that you have to make an account, which means it won't be a complete free-for-all.
Making an account is pretty easy, because in addition to the standard email address login you can also choose Google Sign In and have an account more-or-less instantly. I may add Facebook or other login possibilities if people want them.
As an added bonus, now that people can make accounts, there are all sorts of other fun things that I may be able to add to the site...if I get enough traffic to justify it. I could have people compete for best theme, save games more permanently, or save and share the Customizable Rules 2048 variations. It also brings us much closer to having high score boards.
cesoid.com isn't the only place you can make custom themes, but it does do some things that other sites don't. Just to name a few:
So, yeah, have fun. But not too much fun.

This doesn't take much explanation. [Edit: But as you can see below I wrote a lot of words anyway.] You can explore a fractal with panning and zooming. There are a lot of these out there, and actually I have two of them, and maybe I'll release the other one later. There are a few things I like about mine that others do not have. The one I'm putting up now is the "slow" fractal (Mandelbrot set, in case you care about that sort of thing) explorer. The "fast" one (which is literally about 100 times faster) doesn't have some of the things the slow one has, because I learned about how to make it go really really really fast after I made the first one, and I haven't had time to apply the same features to the fast one, partly because it's harder. But, as I was saying, here's what's cool about my fractal (Mandelbrot set) explorer:
By the way, this will use up a lot of processing power, so if your computer slows down and starts making a lot of noise (because of the fan), that's why. If you have a laptop and it isn't plugged in it will probably run down the battery much faster than normal. However, this is nothing compared to what happens with the "fast" version that I will (hopefully) put up later. That one requires a warning up front, because, for reasons I'll explain later, it cranks up the fan in my computer faster than I've ever heard it before, and starts making basic parts of the interface harder to use. It's kind of like when Arthur Dent asks the ship computer to make him a cup of tea.
Oh, and another thing, in case you're one of the crazy people who reads all the way through these things: If you zoom in "too far" you start getting double images or blurry images. That happens because the numbers that your computer is calculating are so close together that the computer is having trouble telling them apart. Cheers!

I'm clearing out the backlog of things that I started but then didn't feel confident enough to publish on the site. This is mainly because this website is failing to get enough traffic to sustain work on it 😢 I have a grand finale lined up to go live in two weeks: Custom tile images for 2048. It is, by far, the most likely thing to bring people to the site. I know this partly because my site shows up in a Google search for things like "Customizable 2048", and is ranked higher than some sites that claim to have hundreds of themes being created per day. I do have a "Custom 2048", but it's for customizing the rules. Most people seem to want to customize the tile images. At any rate, either that will take off like a rocket or flop, or somewhere in between. If it doesn't take off, unless a miracle happens within the next few days, this will be the second month straight of traffic slumping instead of exponentially rising. But I can't release custom tile images now, because I'm going camping in Cape Cod for a week and this custom tiles feature has the potential of requiring heavy moderation and immediate bug fixes. So if I want to bring in some traffic this week, it's got to be something else.
Anyway, here is a screenshot of the thing I'm supposed to be talking about right now:
So, this is a potentially awesome thing, but it is more of a toy or learning tool at this point. If I can get it into a more complete state, you could use it to program real projects, and in my incredibly not humble opinion, it is worth a trillion dollars.
As is the case for most things, This Has Been Done Before™, but all the examples I could find were either not taken seriously and just used to teach children programming (though mine isn't even capable of that yet), or were not refined enough to be user friendly, or just basically amounted to taking normal code, putting it into blocks, and connecting them to each other in a way that is more confusing to look at than typing it into a text file. Of course, I'm biased at this point.
It's greatest shortcoming can be seen by looking at the code that is produced. It does nothing. Some very important elements are missing, most notably: variables, input, and output. The program amounts to a sort of calculator with hardcoded numbers. (I partially implemented variables, but they are very buggy. You can't access them graphically, there are no buttons for them, but you can type them into the code, and the resulting graphical changes may or may not make sense.) It is, as they say, unfinished, which is why it has been moldering. At any rate, if enough people like it in its unfinished state, maybe people will share it with others and it will get a bunch of visits and it will justify developing it further.
