    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.

Nice algorithm for generating many different colors. This is the kind of color set you could use when plotting many different variables in the same plot.

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

(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.
