What will they think of next?

To think something like that in your mind is one thing. But to actually build it is really cool.

Wow, that's pretty cool. But, there's still the issue of balance that has to be reckoned with, especially in high speed motion.

I think it's more of a demonstration that gears don't actually need to look like gears, than an actual geartrain design. It would work well for an art automata or something like that.
