  95. This shows one of the six regular 4D polytopes rotating in 4D.
  96. Inspired by H.S.M Coxeter's book "Regular Polytopes", 3rd Edition,
  97. Dover Publications, Inc., 1973, and Thomas Banchoff's book "Beyond the
  98. Third Dimension: Geometry, Computer Graphics, and Higher Dimensions",
  99. Scientific American Library, 1990.
