    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.

s=S(t/8.5)*n is a little nicer but I'm still experimenting before another remix.

Augh - trying to fit x.fillStyle=R(i*n,j*n,i*j) in there but can't figure out where to cut.
