OpenProcessing

OpenProcessing is a community gallery of creative coding sketches you can remix. You browse p5.js and Processing sketches by artists and students, open one to run it, and fork it to tweak the code. It also offers class tools for teachers, which makes it a well-run home for generative art. When you arrive, you see featured sketches, and you can search by topic or browse what is new. It is a good place to learn by example, because every sketch you like has code you can read and change. Note that the site sits behind a Cloudflare check, so automated tools may be blocked, but a normal browser should work. Pick a sketch that catches your eye, read how it is built, and make a small change. Whether you are a beginner or a seasoned coder, there is plenty to explore here.
