Shift Happens
Click a thumbnail to see its larger version and description.
Six unequal gears separable aand rotatable in groups of three.

Shift Happens is a meshing-gear puzzle in the same vein as Pentafold and Gear Fold. Bram Cohen asked for a set of six gears with an unequal number of teeth. After some discussion, he proposed the numbers 10-20-16-12-18-15. The initial idea was to have the gears in a triangle, but the gear set would not mesh that way. The alternative was a hexagonal pattern. As Pentafold and Gear Fold are rather floppy due to their hinges, Shift Happens uses a shifting mechanism similar to Gear Shift, but flat instead of spatial. This does not change the puzzle with respect to solving.
This puzzle attended the design competition during IPP35 in 2015.
