    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.

Well done! Try to change "v,32,32" to "v,32,.02" or "v,32,.05" or "32,.2" to archive some interesting effects.
u/KilledByAPixel

you probably already know but you can remove the hsl comas to save a byte hsl(${a/7} 69%50%
u/pavel

That does not work in Safari, the color will always be black.
