Step right up, my pretties, and crawl into the belly of the beast! Place those eager feet on accepting pedals, and the Fledgling nearly takes flight!

Nearly, of course, because Fledgling is a massive metal skeleton at Maker Faire Bay Area 2011 and is not capable of flight. To which Irene says, bring it on over to the East Coast and we'll see if that's still true!

But anyway, being a large, flightless bird is OK, because it is still one impressively constructed fowl, and looks cool enough just chilling out in the sun with human beings in its metal rib cage. It's almost as if the bird has eaten them whole for nourishment, for it is their energy that powers the wings of this impressive art piece, designed and built by the unshaven chap seen in the video.
