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.

A 8-sided die based on an isohedral non-regular octahedron. The faces are identical scalene triangles. The numbers are supported by an inner sphere, in turn fixed to the outer polyhedral shell. The number to be read is that on the face which doesn't touch ground. First version, monochrome.

A 3D projection of the 8-cell, or Hypercube, one of the 6 regular polytopes in four dimensions.
4D Polytopes (or polychora) are the 4-dimensional analogous of the 2D polygons and 3D polyhedra.
Regular polychora are composed of a finite set of cells (polyhedra), all regular and alike, surrounding each edge in an identical way.
We cannot see a 4D polytope, but we can project it in 3D (in the same way as we make a flat drawing of a polyhedron).
The Hypercube is composed of 8 cubes.
This is a special central projection (perspective) of the polytope, in which no cells or edges intersect each other. It is also called a Schlegel diagram.
