Originally found here and here (second link no longer works). This was a fun crafting project I put together when I was at Olson Kundig, in which you print out the designs on card stock, cut them out and fold them, then glue them together with a little motor inside to move the legs. I wired it up to an old solar panel kit left over from a former intern’s experimentation, but it only ever limped along. When connected to a battery pack, though, it ran like a champ!
