Designs by friz
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.

Sterographic projection of the Tetrahedral group T. The sphere subdivided into fundamental triangles is projected from the north pole onto the equatorial plane, leading to a pattern of lines and circles. In this case the north pole (centre of projection) is taken on the 60° vertex of a fundamental triangle.

Sterographic projection of the Tetrahedral group T. The sphere subdivided into fundamental triangles is projected from the north pole onto the equatorial plane, leading to a pattern of lines and circles. In this case the north pole (centre of projection) is taken on the right angle vertex of a fundamental triangle.

Sterographic projection of the Tetrahedral group T. The sphere subdivided into fundamental triangles is projected from the north pole onto the equatorial plane, leading to a pattern of lines and circles. In this case the north pole (centre of projection) is taken on the midpoint of the long side of a fundamental triangle.

One of the 3 polyhedral symmetry groups. The tetrahedral group features 24 identical spherical triangles (fundamental regions) with angles of 90°, 60° and 60°. This is the symmetry group of the tetrahedron, and of many other uniform polyhedra.

One of the 3 polyhedral symmetry groups. The octahedral group features 48 identical spherical triangles (fundamental regions) with angles of 90°, 60° and 45°. This is the symmetry group of the cube and the octahedron, and of many other uniform polyhedra.
