    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.

I have been golfing on this for some weeks

unfortunately I lost the origins of the code, but it was a post on codepen

what is the purpose of -t%1?
u/danny@hille.dk

gets the fraction if t: Try writing ´throw t%1` in a dwitter editor
u/danny@hille.dk

Well i guess it's leftover code from the depth calculation golf :-) doesn't seem to do much now :-)
u/UEZ

Yep, removing it can save some bytes without any effect...^^
u/UEZ

Btw, looks very nice. :-)
