Mostly in CVs Charles Gilman distinguishes Wellisch versus McCooey/Glinski. Here are applets for those two too, /play/erf/Glinski.html, and /play/erf/McCooey.html. What are the differences between Glinski and the older Wellisch in piece-type topography? Is the demarcation two-fold, or is there a difference between Glinski and McCooey in philosophy of hexagons? Where do Wellisch and Glinski diverge anyway?
There are many modern Indian cvs. Here's an applet for one: /play/erf/MayaChss.html.
