Karma
Karma is a yet-to-be-created framework for creating very simple Sugar activities using javascript and html5. It is not intended to create powerful animations, simulations, or reusable artifacts. PyGTK and pygame are much better tools for that purpose.
Team
At this time, Bryan Berry and Felipe Lopez Toledo "SubZero" are exploring Karma as a Google Summer of Code project. BryanWB will likely serve as the mentor and Felipe as the GSoC participant.
