3D Printer Templates for Two Wang Tiles

This Demonstration extends Wang tiles for Turing machines that have two symbols and , and possible states , ,. A rectangle and a disk are used as symbols. States of the machine are represented by a regular -gon. The operation of the machine is represented by these tiles:
The first is called the alphabet tile and the next two are merging tiles. The last three represent action tiles: , and .
Choose "palettes" to save the graphics in a form for 3D printing.

This modification of Wang tiles was introduced by Robinson [1]. We added the action tile.
