    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.

u/Xen

nice, try: p=y=t*t*t%255; and play with your strokeStyle ;-)
u/Xen

something like: x.strokeStyle=R(y,y/2,y%t) slow to start but nice effect.
u/koloskus

ooh thats pretty slick, thanks for the suggestion!

You'd save a lot of characters just by removing newlines.
u/Xen

for each newline removed they would need to add a "," ...the main save would be for(i=5:i--:x.drawIma...)

lessons learned. also, possible bug? on dwitter.net it shows 144/140, on u/f0rkbom it shows 138/140
