Regrettably Pilas went with QT so it's not easy to integrate with XO.

Interactive mode would make it really nice to show concepts and get instant feedback.

I've updated a prototype of a new activity:

It's an interactive authoring tool!
Note it requires gvim currently.

fixing #59 would make the interactive experience more compelling

Awesome!!! I really need to sit down and play with this. An interactive mode would be amazing...
