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 🤔
