# I Like Icosahedra
# by Ira Greenberg.
#
# This example plots icosahedra. The Icosahdron is a regular
# polyhedron composed of twenty equalateral triangles.
# fjenett, 2010-03-11:
# This is by far not an exact translation of Iras code. I removed
# the unneeded Dimension3D class, simplyfied Shape3D and improved
# the Icosahedron class. That and the rubyfication ...
