    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.

Feel free to play around :D... Might make this into something better soon if all goes well, but that's a secret for now...
u/BirdsTweetCodersDweet

You can also change c.width^=0.5 to c or delete it entirely (d/7538) to get other weird effects...
u/BuRRak

t/frame instead of c.width^=0.5 also makes it look cool
u/BuRRak

and changing the variable a also makes it nice

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.

Incredible!
