I have been using it to create some interactive graphics and animations, but also to study equations of motion in Physics, Chaos, even to develop installations and games, and I have been enjoying it a lot.
When studying the library, I found myself copying and pasting a lot of boilerplate code, so I decided to build a collection of sketches that I could use as a catalogue of my experiments. Something similar to OpenProcessing, but with my own sketches on a local installation.
I quickly realized that it could also be useful as a learning resource for others, so I published everything online:
Screenshots, or it didn't happen
Check out all the sketches and let me know what do you think about them!
