    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 is very heavy on my laptop! Remixed here: #4841
u/joeytwiddle

Very nice though. It plays tricks on my eyes, seems to be always growing.
u/New_Core

Sometimes dwitts gets heavy here also scrolling down the list.. most times it help to copy the share link and look at it alone, but yea this one can be heavy, running lots of filters and "gCO"'s
