    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.

It looks a bit more toasty if you multiply t*2 in i*160-t, just couldn't figure out how to fit it.

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.

This shows the pattern traced by a line directly between the Earth and Venus as they orbit the sun. This pattern is pretty ancient, for example discussed in the book Quadrivum about the old academic relationships between art and science. This type of pattern may be helpful to appreciate the concept of Orbital Resonance in a planetary system.
