Hi Shapeways fans,|
Tracker Ball is based on an idea by Bram Cohen. Tracker ball is a twisty puzzle that looks nothing like a Rubik's Cube. It has one big spherical gear with 20 teeth (icosahedron) and three small spherical gears with 8 holes (octahedron). The big sphere gear rolls like a tracker ball supported by the three smaller sphere gears that act like ball bearings.
In its solved state, the green tooth of the tracker ball is inside the green hole of one small ball, the red tooth of the tracker ball is inside the red hole of the second small ball, and the blue tooth of the tracker ball is inside the blue hole of the third small ball.
