    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.

Oops this shows all factors, not just prime factors
u/donbright

hee hee sorry my description on the original was slightly misleading
u/donbright

you have golfed it down to where you might actually be able to do something only with prime factors
u/donbright

holy smokes... i just realized something. if you express an integer using this method, there are only 2 to the twelfth possible representations, which is 4096
u/joeytwiddle

Even fewer, since 4, 6, 8, 9, 10, and 12 never appear alone
u/joeytwiddle

They all light up at t=13860, after 3.85 hours #waitforit
u/joeytwiddle

For seconds/minutes use S(a=i/9.55) and d(60+i/4,i)
u/joeytwiddle

To see factors of odd numbers only, and quickly: i=N=t*22|1

inspired by @Purpzie #interference i simplified an old one ... what fascinates me is the entire pattern is based on modulo function applied to Quadrance, there is no cosine, sine, trig, or even really commands to draw colors based on posiiton. #waitforit
