The staff monkeys here at jwz testing labs have approved the toy to the right for your use. Not only does it glow in the dark, but it makes very satisfying clickety noises when you point the sticks at the balls. There aren't enough pieces to make anything menacingly large, though; we hypothesize that fun will increase linearly with number of sets.

Warning: we find that it is not as much fun assembling things with the lights off as we expected: the balls roll away.
