    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.

Thanks for all the kind comments :) for those interested: the key is in the parity bit p=i&1 this allowed me to combine two different but similar functions by multiplying parts in an out on each iteration. You should be able to pull the two apart into something more intelligible.
