    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.

liked this method alot. remix https://www.dwitter.net/d/2037
u/hypothete

your noise generation here is slick, is this a technique of sorts or just trial and error?
u/recursive

Both. I wanted to be random, but I didn't want pure static. I wanted nearby pixels to have similar levels.

I'm mostly just obsessively golfing the one cool demo I did and using the excess characters to add cool things... I should figure out more demos

Btw - you can change font to '14em a' or similar to save some bytes

If you don't need a very exact pi you can also shave some bytes off.
