    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.

amazing! how many extra bytes to have it less pixellized?

Only +2 for 1/4 HD: d/18436 but your CPU will cry :P in fact full HD fits but you have to start measuring the speed in seconds per frame.

Impressive!
