This sculpture - called Geometric Death Frequency-141 - shows a liquid splashing in a 6m x 15m invisible cube. Made entirely of small black spheres, it's so complex that it's being completely manufactured by robots, who glued the balls one by one.
The sculpture plans were created in a 3D program by Federico Díaz for MASS MoCA 2010 - the Massachusetts Museum of Contemporary Art in North Adams. Díaz programmed the CAD software, using particle physics to simulate the liquid. Once he got the frozen shape he wanted, he created another 3D manufacturing software, taking the spherical pixels into real 3D space. For that he also had to create his own custom "3D printing" rig that uses robotic arms and dual glue dispensers.
