    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)

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

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!

Have your say regarding pixelated dweets: https://github.com/lionleaf/dwitter/pull/216

u/joeytwiddle

(The CSS in this dweet works in Chrome and Safari, but not Firefox)

Although I think the consensus has emerged already.
