Paying our respects to John Horton Conway (1937-2020)
This challenge comes from Robin Baumgarten 🌱🛠️ (@Robin_B), an Experimental Hardware Game Maker and blinkenlighter in Berlin who has supported some of our past events. Robin writes: "The [Graffathon] sounds awesome ... I've been reading a bit about cellular automata again recently, might be fun to try to adapt them to the LED strip arrays!" 🎄
Also known as Conway's Game of Life, this is a relatively simple algorithm to implement, that creates complex and visually intriguing dynamics. Check out the excellent introduction with sizecode by Inigo Quilez at https://iquilezles.org/articles/gameoflife/
We will have some LED strips on site which you're welcome to hack on. If you want to build an LED matrix, like the famous Biowall in Lausanne or maybe just a wee bit smaller.. the parts are best ordered online. You can find instructions and sources for an Arduino-based LED array here.
