    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 had implemented so many more features, like a nice gradient while drawing, but had to scrap a lot to get it in 140 characters... :( DwitLonger please!

Neat! At first thought it was a lopsided <3 :P

its all in the codegolf, you'll learn some shortening tricks by looking around here, t?x.lineWidth=3:x.t(960,540)

Ooh, that's a really neat trick, thanks! And here I was, so proud of my for loop :p

there will be a messaging system shortly, will come in handy for shaving that last pesky byte
