    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.

Splits 1920px×1056px canvas into 20×11 grid of 96px×96px tiles. Once every 9 frames fills a random tile black or white. Every frame picks a random 2×2 group of tiles and draws it onto a random 1×1 tile at ½ the size.
