VRML Models
Several pictures bear links to VRML models. Those can interactively be viewed by means of a free browser plug-in, e.g. Cortona3D.
It should be noted however, that some Browsers like the new Microsoft Edge or Google Chrome (since version 42) don't support any add-ons!

Javascript
allowance will not be a must within this site. Even so, some few of the VRMLs might not work, Further the improved color-softed display of incidene matrices could not appreceated then (but, for sure, all the matrices would be completely visible nevertheless).
