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.
there are a few handy compression tools/dweets @ https://dwitter.net/h/compressor . They don't all work, so look for the ones with a lot of Awesomes, like: https://www.dwitter.net/d/11852 . I've been a long fan and user of Dwitter but my main (and perhaps only) complaint is the strict 140 char rule. It has given me equal measures of inspiration and frustration, hence why I created the spin off site, https://codegolf.tk which has 3 categories, 140b, 512b, and 1024b to allow for more sophisticated demos while still giving credit for the 140b achievement. :)
