In my spare time, I created several creative code playgrounds where you can create generative art using code:
Dittytoy: Create your generative music online using a simple Javascript API (blog post).
OneShader: One fragment shader and your imagination (blog post).
Turtletoy: an online platform that allows you to create generative art using a minimalistic javascript Turtle graphics API (blog post).
You can support the development by giving me feedback on improving these sites. Feel free to report bugs, suggest improvements, or request new features.
