    u(t) is called 60 times per second.
    t: Elapsed time in seconds.
    S: Shorthand for Math.sin.
    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)
    c: A 1920x1080 canvas.
    x: A 2D context for that canvas.

This is absolutely beautiful.
u/tomxor

Thanks for all the kind comments :) for those interested: the key is in the parity bit p=i&1 this allowed me to combine two different but similar functions by multiplying parts in an out on each iteration. You should be able to pull the two apart into something more intelligible.

Filled truchet tiles, now animated thanks to shaving by @donbright

u/donbright

the thing that strikes me is the black and white balls never move, only their connections.... but it looks like the whole plane is aliv
u/magna

@donbright To achieve that: Starting with a single tile, every other tile is flipped on the X axis. And then to flip a tile, I need to both invert the tile's pixels and also to flip it on the Y axis. Lots of XOR was needed :)
u/sigveseb

Excellent

A brute force approach to circle packing. A lot of thanks to jsgolf slack channel residents @xem and @qfox helped **a lot** reducing my original 167 characters attempt ( https://codegolf.tk/a/152 ), as in actually doing most of it. I honestly did not think reaching 140 bytes was possible.
