Spider Gear was suggested by Bram Cohen
and named by José
. A ball with holes is contained by a cage and six pointy gears. When the ball is turned then the gears follow. Both the ball and the gears are bi-colored. The object of the puzzle is to turn the ball such that it ends up upside down, while the gears are returned to their original position.
