When I started thinking about building something that floats, I started with spheres. I pictured a giant ping pong ball that could hold 4 or 5 people. It would be very lightweight and because it was big, it would hold people + oxygen. Good stuff.
Well, giant floating spheres brought me quickly to Tom Chudleigh who builds beautiful spheres out of wood. These giant balls float in trees instead of water. They are beautiful and truly an inspiration for me; sort of Captain Nemo meets the ewoks.
