These illustrations, taken directly from ScienceU.com pages, are said to be copyrighted by Geometry Technologies in 1999. The first six illustrations are essentially the same as figures from the preprint "Diamond Theory," by Steven H. Cullinane, published in 1976 and with a copyright notice dated 1976.
The remaining eleven illustrations are reproduced here for purely scholarly, personal, and noncommercial purposes.
