Classic Celt (or Rattleback)

The Rattleback is a so called "impossible object", that has its origins in the Aboriginal culture. When you spin it clockwise it rotates normally. When spun counterclockwise, it reverses direction. The objective is to try to explain why the rattleback reverses direction, how is this possible? The size of the Rattleback is approx. 15x4x3cm.
