3D geometry .STL files

Just thought I’s share a cool site, this guy named George Hart makes geometric polyhedra sculptures for a living. link Anyway, I did a quick render of the model on the top of the page, which is a 3D shadow that was calculated a specific 4D object would cast. Ray mir and Ray trans depth are both 10, IOR of 2.41 (diamond.)

[Edit] I would love to animate a camera rotation or two around it, but render times would be prohibitive…
