    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.

#default with transformation matrix setup. Z is zoom factor, A is rotation angle. Go nuts.

wanted to use (1+S(t)*C(t)) instead of (1+C(t)) but oh well

Shaved you some characters and added the +S(t): d/10329
