Hi Shapeways fans,

Magic Gears (a twisty non-puzzle) is a paradoxical set of three identical gears that can both mesh in the regular way and all in the same direction. It was inspired by this YouTube video by Jacques Maurel. Maurel writes: "The paradoxical 2 teeth gear set is used in the 'Mercier differential' (using the torque transfer technology) Patented in 1988 by Renault". Oskar's addition to the work is making Chevron Gears as invented by Andre Citroen. This way the three gears become identical and they can both mesh classically and paradoxically.

I have performed this Magic Gears "trick" to several friends, family and coleagues. I get two types of reactions: "wow" and "so what". Apparently, there exist people who are not aware how gears are supposed to mesh Smile.

Watch the YouTube video.
Buy this magic trick at my Shapeways Shop.

Enjoy!

Oskar
