30 black magnetic pyramids click together to create a rhombic triacontahedron (it’s easier to make than it is to say!) one of the most perfect geometric shapes. Each individual piece of the Ball of Whacks is a “golden ratio” rhombic pyramid. Held in place by 180 rare earth magnets, the design pieces can be formed into any shape you can imagine. The Ball of Whacks comes with a 96-page illustrated creativity guidebook that provides you with tips, inspiration, mental exercises, and insights into the creative process. Among its many awards, the Ball of Whacks was voted “Best Desk Top Toy” by Fat Brain Toys. This new black Ball of Whacks is a perfect corporate gift. Give one to every stressed exec you know!
