    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.

k=[4 bits for y][4 bits for x][3 bits for hexagon vertex]

16*16*8=2048~=1920 so using width
u/pavel

.43~=3**.5/4, 2.1~=2*Math.PI/3
u/pavel

120=0b1111000 so k&120=x*8
u/pavel

I'm using a single stroke and no moveTo. This is a single curve, just lined everything up.
u/pavel

d is horizontal offset, even rows are offset from odd rows. Using +4*t&1 to explicitly cycle the animation every second instead of implicitly cycling every 2 seconds. Longer cycle leads to z<0 and glitches or hexagons that don't reach the camera.

Wow!

I've stared at this for too long... don't think I can get it below 146 decompressed (with Z inlined). Would be rad if we could squeeze those last characters out though and get it down to 140 without compression :)
