    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.

Every possible tic-tac-toe board (and some impossible too)

u/joeytwiddle

Challenge: Every possible tic-tac-toe game (no illegal boards)
u/pavel

Here, but only problem is that it keeps playing after winning: c.width|=k=300,x.font='20em"',b=frame>>4,m=b&1 for(i=9;i--;)x.fillText("⚬× "[b&2<<i?m^=1:2],580+i%3*k,380+k*(i/3|0))
u/pavel

Oh, nevermind. Its missing boards because it doesn't permute X and O fully for each template.
u/joeytwiddle

Good effort anyway!

This uses a modified version of DCT. All data is in 2 magic strings. To create your own: https://pastebin.com/zEH5aH1R copy this to a dweet draft, draw, get your own magic strings.

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.
