I am all about gadgets that are functional, but sometimes I enjoy a gadget that has no value other than to entertain. Frigits are magnetic tracks and contraptions that you can arrange to make your very own marble rollercoaster. The kit includes colorful funnels, tunnels, catapults, and spinners that can be arranged in hundreds of different combinations. Set up your set at work and watch as all of your coworkers will not be able to resist trying out your marble maze. If you were thinking of picking one up, it will run you about $30. [OhGizmo]
