Shapes of the Fourth Dimension Shop Space

This shop will provide collector cards of various four dimensional shapes which I also call 'Polycards'. My plan is to eventually have cards made of the 2189 uniform polychora as well as scaliform and fissary ones. These are stunning and unusual shapes that exist in the fourth dimension that very few people have ever heard of. I discovered many of these in the 1990's and later rendered graphics of them. Currently a small team of polytope explorers are searching for more. If these sell well, I hope to extend these into five dimensions.
