tixy.land: weird website review & sites like it

tixy.land is a playground for visual code golf. You write a function of time, index, x and y, in 32 characters or less, and a 16 by 16 grid of dots animates according to your formula. The page title shows the format, and the idea is to make patterns from as little code as possible. It was created by @aemkei, and it is both a toy and a tiny lesson in how math becomes motion. When you arrive, you can see examples and edit them live, so you do not need to start from nothing. Change a number, see the dots shift, and you begin to understand how the pieces work. It is great for programmers who like constraints and for curious non-programmers who like watching patterns. Try changing one value in an example at a time, then attempt something of your own. It takes five minutes to get going and much longer to put down.

Tips for getting the most out of it

Start by editing an example, one value at a time.
Try sine and cosine for waves.
Shorter is better; the limit is 32 characters.
