The Ball of Whacks has been designed to stimulate new ways of thinking. It was created through dividing one of nature’s most beautiful shapes – the 30-sided rhombic triacontahedron – into 30 pyramid pieces. The result is a fun set of magnetic building blocks with many uses.  Create new shapes and free your mind from other concerns.
