    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.

Shave 3 chars: (i>>5)*C -> i&-31
u/KilledByAPixel

you can also do i>>5*C, but both ways distort the image

I don't rightly know why, but i&-32 seems to work without distortion as far as I can tell
u/KilledByAPixel

Oh wow, nice!
