    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.

The most awesome thing about Dwitter is how the quality of the dweets is constantly increasing. Everybody is learning new tricks and techniques from one another and doing more and more awesome stuff. :)
