Dutch puzzle maker Oskar van Deventer, the inventor of the 17 x 17 x 17 Over the Top cube and other wonderful 3D printed creations, demonstrated his new “Magic Gears Grid” which houses fixed gears that simultaneously turn in both clockwise and counter-clockwise directions when a handle .
Magic Gears Grid is a triangular grid of Magic Gears. As everybody knows, adjacent gears are supposed to turn in an opposite direction, and gears should be gridlocked when meshed in a triangular grid. However, it works for magic gears. Magic Gear Grid has a total of 19 magic gears in a triangular grid, one of which has a crank. When the crank is turned, then magic gears with the green side up turn clockwise, those with the red side up turn counter-clockwise (anti-clockwise). Surprising, isn’t it?
