What you are looking at is a 17cm x 17cm x 17cm Voronoi net of something called the Clebsch diagonal cubic surface. We are using it not for its mathematical properties per se, but to display custom jewelry at retail. For those of you who weren't able to order a sample in the White Glaze material, the print is solid and beautifully smooth, with a very high quality feel to it, completely suited to a professional display environment. Since the White Glaze material is not available right now, it is available here in White, Strong, and Flexible, including the optional colours.
