A Beautiful Ballet of Hoberman Spheres Expanding and Contracting in Rhythm With Each Other

German artist Nils Völker, known for his incredible interactive work, created Bits and Pieces, a kinetic ballet of colorful Hoberman Sphere toys that successively expanded and contracted in a beautiful visual rhythm.

The installation consists out of 108 so-called Hoberman spheres hanging in the middle of the exhibition space. The mass-produced children toys are made from countless interconnected colorful plastic levers and can expand itself to a multiple of their size. Each one is moved by a servo motor and individually controlled by a micro-controller thus organic waves appear to move throughout the space although each single plastic ball simply expands and contracts at the right time.
