What would you love to work on?
modeless: Computer vision for autonomous robots.I've done a lot of 3D graphics and I think working on the inverse could be fun too.  I think a lot of progress is going to be made quickly now that 3D depth-sensing cameras are becoming available.  Most interesting to me are self-driving cars (e.g. the DARPA Grand Challenge robots) or dynamically balancing 2-legged anthropomorphic robots (e.g. Honda's ASIMO).I don't know anyone in the field, so if I was really going to pursue this I'd probably start by going back to school.
