    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.

I prefer this with a slower cycle by having t/99 instead of 9, but I couldn't find another place to drop a character

u/iverjo

You could move f= inside R, like this: c.width=198;a=6+C(t/9) for(i=-99;i<99;i+=a)for(j=-56;j<56;j+=a)k=i*j,x.fillStyle=R(f=k*k*(1+C(t)),f/9),x.fillRect(99+i,56+j,a*S(k),a*C(k))

For those who are wondering h is meant to just represent half the height of the screen. I just wound up using it in inappropriate places because it was roughly the right number for what I needed

Bah, and there I was thinking I'd got there first. I get crazy lag when trying to look back due to the infinite loading, so I've been unable to see what people have done already
