"One of thousands of mysterious stone spheres found in Costa Rica.
These are thought to have been carved by the Chibcha, an ancient
war-like people who used prisoners as slaves and human sacrifices
and built fortified towns in the region of Costa Rica where the
spheres have been found."
Well ~ What do you think?
Looks like one of those rolling stones that Indiana Jones was
running away from in the Temple of the Sun...
