Open Source Projects - Inspired by Brett Victor

This is inspired by Britt Victor's talks on interactive and exporable programming. I'm attempting to kick out these libraries that are kind of best in class as far as their documentation, testing coverage and their support integrate with all the closure tooling. So yeah, inspired by Brett and then maybe not as creative as his work, but the meat and potatoes usability, I want to be as big as possible to make up for that.
