    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.

High resolution Game of Life with a constant ground layer. It will eventually start cycling. To increase FPS swap 2e4->6e3. To hide the ground swap 4e3->5e3.
