Its good to be able to say "I'm just experimenting with the design of networked objects" when you need to rationalize the purchase of toys. I just got the first tiny success building data driven Mindstorms robots. If you have anything, anything at all, you want or need to do, I suggest you don't waste your time watching the video above.
(note: The original screen play for this movie, called for a co-star, appearing from across the globe via Skype, to actually control the robot, which of course would have added to the excitement. That'll just have to be next time. Possibly with a sound sensitive robot aware of the controller even as it is being controlled. Possibly with a 'I'm sorry Dave, I can't do that" sound embedded as error message.)
