I know there's a video in the works for this, but I'm going to share it now anyway. Check out this beautiful creation by builder sadovich7.9! If that name sounds familiar to you it's because he's the designer of the LEGO Ideas Ship in a Bottle. Now he's back with a little mechanical wonder that I can't wait to see in motion, one of DaVinci's concepts for a human powered flight, the ornithopter. There's even a little orrery in the base, what a wonderful detail.
