Buy at http://www.shapeways.com/model/592699... Copyright (c) 2006-2012, M. Oskar van Deventer & Andreas Röver. Looney Gears is a strange eccentric planetary gearing system. Whereas normal planetary gear systems are symmetrical, this one has no symmetry whatsoever.

This particular set of gears was the result of a challenge by Oskar to Andreas Röver in 2006. Andreas found this nice set of all-primary-numbers gears which is about 0.01% exact.

At this moment, it is not known whether there exist exact solutions for this type of eccentric planetary gear systems. Oskar's conjecture is that no exact solution exists. It would make a nice math graduation project to prove the conjecture or find a counter example.
