Fly like an Eagle to the Sea (or across a park)

Like a modern day Leonardo da Vinci. Jarno Smeets develops flapping wings just like a real bird. They use a special motion mechanism built around an Android phone and Nintendo Wii Controllers. His system literally allows him to start flapping his arms to take off and keep flying. It's pretty awesome but you would need to really be in shape to keep this going, 15-20 flaps tops and I'd be down, dry heaving & lungs burning.
