    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.

I haven't actually put the time into understanding how this works, but that doesn't stop me from remixing it!

Logistics map with some bifurcation, still trying to figure out how to make it look pretty tho

u/artfarnaa

Nice, though I suggest provide a link to background info on what a logistics map is and what bifurcation does. We newbies need just a tad of hand holding.
