Cai Guo-Qiang - Daytime Fireworks

This performance from Chinese artist Cai Guo-Qiang shows how Volatile black powder explosions can be controlled and shaped by computer.

Each set of explosions was calculated to paint a different picture. One series of explosions created black smoke clouds that looked like “drops of ink splattered across the sky.” In another, 8,300 shells embedded with computer microchips exploded in a pyramid shape over the desert.
