When it comes to geometric shapes, Jacques Heim, 50, is obsessed. After founding the risk-intensive, hyper-physical dance troupe Diavolo in Los Angeles in 1992, Paris-born Heim translated that passion into full-blown, custom designed stage sets. Included are a 2-1/2-ton aluminum wheel, a 17-foot-long rocking boat and an enormous cube with more configurations than Mr. Rubik’s.
