Perplexus - cool 3D maze. "Like a video game without the electronics."

It may look like a small child's toy, but is anything but. Perplexus is a 3D maze where players maneuver a small marble around challenging barriers inside a transparent sphere. You work with gravity to carefully shift, flip, and twist the sphere to guide the marble. One blogger says, "We’ve found the puzzle to be extremely addictive to anyone who gets started. Because it’s like a 3D video game without the electronics, the very physical nature of playing — turning it this way and that — is very satisfying. In addition, the maze is like a sculpture, [and] the design of the route is geekily brilliant." Amazon, $19.59
