I'm interested in solid geometry (polyhedra, 4-dimensional polytopes) and algebraic varieties (curves, surfaces) and I like to create models of these complex objects. Feel free to ask me also customized designs, for example a polyhedron with given dimensions and features. A polyhedron can be realized in different ways, like ball-and-stick style, solid faces, Leonardo-style, curved edges, and so on. Any one of these objects can be also equipped with a ring and transformed into a pendant or a keyholder. Numbers or labels added to any (suitable) polyhedron turn it into a die.

IMPORTANT: Sort the items by "newest" to see the latest things!

Nearly all models are available also in the new colors. Ask in case.
