    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/donbright

i really like this one... the way it works is really interesting, variable size "pixels" plus blur
u/Agnes

Wait whoops, I just realised the filter doesn't do anything because I apply it before I reset the canvas in the first for loop. The blurry effect is just from the variable-sized pixels. Interesting?

Golfed and slightly cleaned at https://www.dwitter.net/d/5543. Have fun with the extra characters!

(cleaned is referring to some slight blockiness on the right side of the animation, not the code. My code is much uglier :P)
u/BackendForth

Neat! TIL Javascript accepts python notation for exponents.
