    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.

This is different every time you refresh, stop by and see what it's drawing.

u/KilledByAPixel

thanks! yeah it does remind me of these compenhagen patterns a bit, they are pretty cool looking :)

different strategy, draw the board on the first frame, pieces on the rest

ohhh that is good, was too tunnelled in on the setups I'd tried.. good job 🎉
u/TGY

fillText Y=i==52?Y-T:Y+T, but can't animate with this method. Don't think it's going to be possible in 140 ether.

ugh yes. so satisfying
