X-Ball (Magnetic Design Set)

Designed by Roger von Oech as a companion product to the award- winning Ball of WhacksR, the innovative X-Ball presents a playful new way to stimulate creativity. 30 magnetic Xs click together to form an icosidodecahedron. The uniquely angled geometry of the X-shaped pieces allows users to invent their own shapes and designs. The X-Ball comes with an illustrated 96-page creativity guidebook that offers lots of ideas for other fun shapes and creative applications for the X-Ball. X-Ball pieces can also be used with the Ball of Whacks pieces.
