I've added a list of suggested next steps in the development of
carcode: http://code.google.com/p/carcode/wiki/NextSteps
I suggest you read those if you are interested in helping with carcode.
I would be especially interested in having someone work on making
carcode 3D. That could be done in parallel with the things I suggest
on the page above.
