    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.

#improved performance

u/pavel

Original runs at 6fps on my machines this runs at 60fps. I lowered the resolution by a quarter (4x perf) and golfed 13 chars to let me declare all vars locally (2x perf).
u/tomxor

wow! this is a massive perf improvement, the original was impressive but I couldn't really see it realtime. Nice one :)
