## Mathematica PlaneTiling

Geometry: Plane Tiling Mathematica Package

**PlaneTiling** is a Mathematica package for tiling and symmetry illustrations. Author is Xah Lee (me). Requires Mathematica to run.

## RepTiles

Mac OS 9

RepTiles v.2.0.1 is a plane tiling shareware written by two mathematicians Daniel H Huson and ?.

The program is capable of generating *all* possible periodic tiling of the plane.

By the words of the authors:

… for interactively designing and systematically generating periodic 2-dimensional tilings and patterns, study symmetry and 2-dimensional geometry, if you are a mathematician, enumerate possible 2-dimensional crystal-structures, if you are a crystallographer or chemist, design complex and interesting patterns, if you are a designer, or explore a whole new world of fascinating periodic structures, if you are, well, just interested.

This program is a bit mathematical, but can be fun for layperson.
It is a rare tool for crystallographer and mathematicians.

(Note: This program is from 1995 era.
The software downloaded from the ftp site is missing data files, making the software not usable.
I don't have a copy of it.)
