    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.

This is fantastic! How did you compress your js like that?
u/cantelope

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. :)
u/DaSpider

The 140 chars would be better if there were more shortcuts like C(), R(), etc. for functions like Math.random, x.fillStyle, etc.

This is really cool! Does setting the canvas width to -1 make it full-width?
u/rodrigo.siqueira

c.width=-1 is a trick I saw here (probably from u/pavel) that makes width=300 pixels. I used throw(c.width) to see "300". So it's a compact form to create a medium-low resolution image.
u/tomxor

300px is the default canvas width. What's particularly odd is that while setting negative numbers causes default value, everything else that ordinarily coerces to NaN will result in 0. e.g throw Number({}).toString() // NaN c.width={}; throw c.width.toString() // 0
u/tomxor

I guess in c++ land width has outofrange=300 and NaN=0
