This is one of those rare generative art tools that actually solves the reproducibility problem. It wraps p5.js with seeded randomness, so you can iterate on a design without losing the happy accidents. Great for making procedural posters or exploring variations on a visual theme without the usual "I'll never get that exact output again" panic. The output mode is set to image, which makes sense since you're rendering stills rather than interactive sketches. It's from Anthropic's official skills repo, so the implementation should be solid. If you've ever wanted to generate art programmatically but need consistent results across runs, this handles that elegantly.
