Leonardo da Vinci’s Wooden Invention Kits
Da Vinci was many things: a painter, sculptor, anatomist and architect. He was also a prolific inventor and engineer centuries ahead of his time, creating, among other things, a helicopter and ornithopter (a winged flying device). These deliciously geeky wooden models give you the chance to appreciate his work at home or at the office. Just don’t use the catapult to attack your coworkers.
