A 3D projection of the 24-cell, 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 24-cell is composed of 24 regular octahedra.

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.

A wireframe structured icosahedron. A fun and playful object to have on your desk or as a decoration.

Note: I've updated the model with 1.5mm thick wires for better support and material choice.

Algorithmically eroded virtual terrain, 0.2mm detail, bottom hollowed out to reduce volume, wall thickness: 2mm. On the underside is the reverse of the terrain: with lobed hilltops and steep valleys.

A Geodesic Sphere.

A truncated icosahedron which has the pentagonal faces stellated outwards and the hexagonal faces stellated inwards.

Also available in a 100mm version.

Little house with big bed and bedside tables for lovers...
Limited edition.

One of the five platonic solids. A wire-frame, regular dodecahedron, which has 12 regular pentagonal faces. A handy visual aid for anyone studying polyhedra or the platonic solids.

an object that can only exist thanks to 3D printing! These 5 triangular pyramids are not connected but form an icosahedron.
