    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.

best fullscreen. Couldn't have done it without the help of the dark knight, who prefers to remain anonymous. :)

u/donbright

yeahhhhh!!!!! cool
u/cantelope

there's an odd bug in chrome where if hardware acceleration is disabled, or the dweet appears far down the page, the arcs close their paths and create unwelcome diagonal lines. I have a more robust version but it does not fit in 140b.

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 :)
