Canadian Tech: SpringDance

Waterman Polyhedron in SpringDance
(click for larger view)

SpringDance by Alan Ferguson is a Delphi-based implementation of Gerald de Jong's Struck concept. Above is a Waterman Polyhedron (#2002), defined by all vertices in an isotropic vector matrix out to some maximum radius, and including those of lesser radius which preserve convexity. Their volumes are always whole numbers, vis-a-vis the standard of unit volume: an IVM tetrahedron.
