If you've seen any of the Leonardo da Vinci invention sketches then this video will probably impress you. If you're an engineer you made need to change your shorts after watching this, although it must be said, this may or may not prompt the reckless mis-use of ceiling fans worldwide.

Leonardo da Vinci knocked together some pretty cool inventions, and this video definitely seems to be inspired by some of them.

I have nothing further, semi-intelligent or otherwise, to add at this point.
