The 20Q ball takes the classic game and puts it into an electronic super brain the size of a tennis ball. All you have to do is come up with something (animal, vegetable, mineral or other), and the ball does the rest, asking the classic questions (as well as some not-so-classic ones) to figure out what youÆre thinking. But what makes it creepy is the mind-reading-like accuracy of the electronic brain as it unerringly nails your "thing" time and time again.
