    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.

This was only running at 20 fps on my phone when I wrote it so results may vary

u/Galaxtone

.... Maybe add t/=3

Looks much better with that

Just messing around with a dweet so I get the hang of the limits. Also made a little thing so I can work on dweets offline: https://github.com/stonehippo/FauxDwitter

Ha. Is it kosher to break out of the function definition body like that? Seems like something u/lionleaf might have on his "to remove" list. :)

You can see here new patterns every iteration, kind of relaxing just to watch.
