    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.

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

This is superb
u/rfs

What is your process for making these? incredible
u/taupelink

thank you! lots and lots of trial and error, lately aided by https://capjs.3d2k.com/ I keep playing around with variations, e.g.: for the Y-coordinate, k+i*Y,k-i*Y,k+i/Y,k-i/Y each have a different effect
u/taupelink

for those unfamiliar with dwitter-style compact JS code: for a typical dweet of this type, each frame draws a bunch of rectangles. each rectangle has random coordinates for its upper left-hand corner. the RGBA (color and opacity) of the rectangle depends on those coordinates and on some other parameter that gets modified with each step. The dimensions of the rectangles shrink over time, thus adding finer-grained detail

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!
