4D Explosion -- Part 2
4D Explosion
April 2007 -- The second part of this 2-part series shows how to "explode" the 3D shadow of a 4D icosahedron (the 600 cell, see April 2006's Model of the Month) into a bunch of tetrahedra, then "join the dots" with long struts to build a kind of "meta-hyperdo!" Get the concept from the 3D Explosion, featured last month.

Many thanks to Marc Pelletier for suggesting this series.
