    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.

Looks nice with n=_=>S(t*_)*99+166 and R(n(1),n(2),n(4)) as the colour

This is almost what I see when I close my eyes in the dark.

Kudos for the idea of using fillStyle and fillRect as strings.
