    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.

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 :)

Change the f assignment at the end to f=t*X/Y&1 to animate. I couldn't shave another byte to fit that.
