    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.

#spirograph generator

u/pavel

I believe this generates all valid spirographs, at least the circle with a small pencil hole rolling in a circle ones.
u/pavel

The incremental drawing is not parameter aware so at the extremes its too slow / too fast and choppy
u/pavel

I was gonna improve this by using the period of a spirograph but gave up deriving it.
u/pavel

I think the period is the denominator of 1-1/m expressed as an irreducible fraction.
