Hi folks, I've put together a simple interactive polyhedron viewer which might be of interest. It requires a web browser that's current enough to support html5, and JavaScript has to be enabled, but that's pretty much it. Here's the URL: http://karzes.best.vwh.net/polyhedra/polyhedron.html You can click-and-drag the individual polyhedra to rotate them, or you can make them spin around automatically. Some filters are available at the top, based on classification and on rotational symmetry. Please note that the rotational symmetry designations are deliberately broad and imprecise, so please don't flame me for their lack of specificity; it's intentional. I should add that the click-and-drag functionality won't work with a touch screen, so you'll want to use a real mouse to use the full interface. Anyway, let me know what you think. Tom
