Tessellations
To tessellate means to cover completely with one or more geometric shapes in a repeating pattern with no overlapping shapes
and no gaps between them. We have prepared tessellations (mosaics) with almost all our shapes including pentagon & decagon!

Poly
Poly is a shareware program for exploring and constructing models of polyhedra, produced by Pedagoguery Software Inc (Canada) .
Poly will generate and print out nets of 126 different convex polyhedra built with Geoshapes / Geofix. It shows all the Platonic,
the Archimedean and the Johnson solids, in addition to Prisms and Anti-prisms and Geodesic Spheres up to frequency 6.

Poly Pro
Poly Pro is an enhanced version of Poly that adds three-dimensional export capabilities.
Poly Pro will export polyhedral models as 3DMF or DXF files that can be imported into three-dimensional modelling programs.

Stella
Great Stella is a program for creating polyhedra and printing their nets. It includes the Platonic, Kepler-Poinsot, Archimedean,
and all other uniform polyhedra, as well as their duals, and all their stellations. Also lots of other features.
Small Stella is a cut-down version with fewer models.
