Black plastic sphere, about six inches in diameter, looks like a billiard ball – except there's a transparent window on the flattened facet base, and there's a murky liquid inside, and a multi-sided floating die inside with messages like "Ask again later." It's akin to those "yes/no executive decision makers". I'm not sure if they were introduced in the 50s or the 60s, but they still make them.
