I started learning about organic algorithms yesterday from this Khan Academy post. That helped me realise two things: 1) there's a well known algorithm called Perlin noise used in Tron to create natural, smooth randomness; 2) there's a LOT to learn about how to model things that look organic!
I've always found beauty in things that flow, like objects with perfect curves and rounded rocks by the beach. So I'm likely to go down this path and learn more. I bought a (self-published!) book for this called The Nature of Code by Daniel Shiffman and have started reading. Most of the next few projects will likely draw from that book.
