This toy was a clear hard plastic sphere, about 10-12" in diameter which
contained about eight colored cups glued in various positions inside it; the
first cup had a mouse-hole entrance at the base that would allow you to roll
a small marble-like ball into it and then start the game.
The object was to rotate the sphere in such a fashion that the marble would
land in (be caught by) each of the colored cups in succession. It took
quite a bit of coordination, and I had it mastered after a while.
Does anyone know what this thing was called and who made it? I'd like to
try finding one on eBay.
