    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.

Stole the code from here: https://codegolf.tk/a/136

That's cheating, pure and simple. The goal here is to do awesome stuff with really little code. Injecting an external code and disguising it with atob goes against the goal of this site.

Shouts back to Xen - this is really a minor tweak on his idea.
