    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 like this trick of re-using the same args for moveTo and arc back to back. The first two args are x and y for both and moveTo ignores extra args.
u/magna

YES!

I have been golfing on this for some weeks
u/danny@hille.dk

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

The depth trick was lifted from one of u/cantelope dweets

u/pavel

Whoa!
u/Qwitter

u/UEZ

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. :-)

good remix of d/10212 :)
u/keithclark

Yes! It's totally based on your dweet yonatan - thanks for the link to the original. I found this in a text file from last year but couldn't remember who did the original.
u/keithclark

I also had this version: for(k=i=1e3;z=--i/9;x.fillRect(k+S(m=z%1&&k*j|5)*r-z*C(j)*6,540+C(m)*r-z*S(j)*4,s=5e3/z,s))j=i/k+t,r=1e4/z,x.fillStyle=R(a=99+S(j*9)*99,a,a) but wasn't happy with the rail
