Recursive tiles are a frequent subject in OpenProcessing, the platform where I publish my Processing sketches. This platform is like an informal/ colaborative/ gigantic criative space where everyone shares his own creations and reuse others creations, called sketchs in Processing. Most the source code is available.
It’s like a team developing in a colaborative space. But here the people don’t known each other, it’s just the pleasure in participating in something big and showing their skills and art. This last sketch I made has code, at least, from 3 other creative coders. Is a good pratice to make a fork of the original sketch or make a reference of the author.
At the end, each creative coder prusuit is own vision and original criation. https://www.openprocessing.org/sketch/908224
