    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.

u/joeytwiddle: that's the whole point of this demo, the lighting is just there because I had to compress it and had leftover space
u/f8f82804

you can see this concept implemented without compression in d/9676
