I want to see someone build an actual working transformer.

And I don't mean like the life-size Gundam replica that doesn't transform. I mean, I want to see someone build an actual object that has all of the motors and actuators and such to convert from car to robot and back again. Doesn't have to be full size, doesn't have to actually "Walk" or drive or anything. I just think it would be an ultra-cool engineering project.
