Aza has also released the Algorithm Ink website, which uses ContextFree.js to create an open source art gallery. Using Algorithm Ink, you can load, tweak, and share generative art through a web interface. When you see something you like, you can view the source for the artwork and use it in your own creations. Very cool.
