    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.

It's cool to see how just plain circles can make such interesting patterns.

??????????? Messing around with circles

u/Natsumi

I'm a newbie to dweets, but this is pretty nice. If you want to make it go slower, change t/2 to something like t/5
