Gizmo Gears
Above:Variant "Treo" - Scrambled
Click a thumbnail to see its larger version and description.
A puzzle with two intersecting circles and bandaged pieces. Produced in low quantity in four different variants.

This puzzle is one of Douglas Engel's patented creations made in low quantities. It is covered by the same patent as Battle Gears, Dancing Gears and Magical Gears.
Compared with the other puzzles the cuts have twelvefold symmetry. The puzzle is unusual in another way because it behaves bandaged.
So far it is unknown whether these puzzles are truly bandaged or jumbling. This question is all about the rectangular piece in the middle. Carl Hoff animated a repeatedly cut up version of this piece. The 5th image here shows the result. It seems like the cutting up doe not come to an end. Therefore the puzzle would be jumbling.

Gizmo Gears comes in three different versions which pieces are differently colored. The names of the variants can be viewed with each images caption.
Gizmo Gears was an entry in the design competition during the IPP25 in 2005.

The puzzles can be obtained directly from Douglas Engel who makes them with laser cutting
