    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.

Brilliant piece of #art, #gingerbread #birdman #stainedglass window :P
u/rodrigo.siqueira

Some good parameters, change the last number instead of ".62" try: .55 or .43 or .73 or -.5
u/jellyedwards

So nice! Variations are great too!

Axon formation around a multinucleate alien cell

u/sigveseb

Nice!
u/Toby

Fab! Do you have a source reference for the kind of iterated formula you're using?
u/rodrigo.siqueira

You can see the original equation by changing the to "s=70" and the end to: a=1-b+Math.abs(a)
u/rodrigo.siqueira

It's based on the "Gingerbreadman Map" #gingerbreadman https://www.dwitter.net/d/14641 I don't understand the details but I know that "Even the simplest mathematical expressions, when interpreted as dynamical systems, yield fractals."
u/Toby

Ahhhh yes of course! I remember Gingerbreadman now! Thank you Rodrigo!

very nice, hopefully as I slowly understand more elements of this I could eventually make something of that caliber.
