    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.

u/pavel - i was just thinking about trying something similar, but you beat me to it. well done!

u/yonatan - i was not aware of Path2D. thanks, and well done! i also see my T could be optimized (leftover from a previous iteration)
