In addition to illustrating how icosahedral quasi-equivalent surface lattices are formed, it has images of all of the icosahedrons that can be generated (from T=1 to T=100) along with paper templates which can be used to make your own models.   The theory of quasi-equivalence was posed by Caspar and Klug in 1962, and this allowed the first understanding of icosahedral virus structure.   Dr. Caspar's web page  talks more about quasiequivalence.
