    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.

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)

Neat! TIL Javascript accepts python notation for exponents.

Nice effect! 22 FPS on my machine, in Firefox. Surprisingly, it runs much slower in Chrome and Edge (4 FPS)
