Dutch artist Theo Jansen is most famous for his Strandbeests--walking kinetic sculptures that look like alien machines. They inspired Blaine Elliot of Santa Barbara, California to build this bicycle which locomotes similarly. It's called the Walking Bike.
Elliott and his colleague JP built a 3d model to test the functionality of Jansen's leg linkages on the bike. Then, over 6 months, they assembled about 670 pieces into the finished machine. You see more photos and specs here.
