    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.

great colors. if you make i/t/S(t/10) it is pretty funky
u/donbright

make a = i/t/S(t/10) i mean
u/rpearl

that's a cool edit! totally different but somehow similar

Oh my god, hypnotic!
