Coding Challenge #30: Phyllotaxis
3,446In this coding challenge, I continue one of my favorite subjects: Algorithmic botany! This video covers the subject of Phyllotaxis, what it is and how it can be used to generate sunflower-like patterns inspired by nature. Code: https://thecodingtrain.com/challenges/30-phyllotaxis
