We've all (well...) seen one. The four-inch
diameter black
ball with the
eight on it that looks a
giant version of a
pool ball. You ask it a
question and then turn it over. Up from the
indigo pool of infinite
mystery arises the ghostly answer inscribed inside a
triangle in some
alien font. "Reply hazy. Try again."
From what strange abysm of inventorhood comes this taunting apparation? Who makes them? Who sells them? Why? We should not ask. It is a mystery.
