    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.

Amazing! Welcome back, Nystrand. I still remember the B&W version of this one (/d/14899). And your dweet d/4388 (Sierpinski witchcraft) is one of the most amazing I've ever seen. Thanks.
