    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.

Only +2 for 1/4 HD: d/18436 but your CPU will cry :P in fact full HD fits but you have to start measuring the speed in seconds per frame.

Into the abyss of rectangles #recursive

u/DaSpider

Where is the recursion?
u/rodrigo.siqueira

Each [a,b] is defined by the previous state of [a,b], so it's actually iterative.. It's based on IFS (Iterated Function System) with transformations are based on a probability.
u/sigveseb

That shading ends up looking really nice!
u/tomxor

Yeah, really nice texture!
u/lulasz

Looks like pencil drawing 🤔
