Core Shapes and Supporting Shapes of The Mitre System.

Back in 1998, I (EPJ) noticed the Fisher Pavers over at Adrian's site. I considered these carefully designed heptagons and squares quite clever. They could make some very nice designs, but I didn't find them chaotic enough. So, I started playing with Autocad LT, trying to find something better.

1. No fault lines across the tessellation in any direction.

2. Ability to make squares and rectangles.

3. No sharp angles -- they break too easily

4. Under a modular layout, the ability to lay out a design with minimal cutting.

5. Spirals and other curves should be possible by using differently colored bricks.

6. The tiling should be able to interface with the modules of other tiling systems.

7. The tiling should use few pieces.

8. The ability to make both periodic and nonperiodic designs is desirable.

9. The pieces must be of similar size. (Dodecagons and triangles won't work for weight-bearing floors)

Semiregular Dodecagon-Triangle design by Archimedes. Can you find all 8 semiregular tessellations?

I'd gotten to know Miroslav Vicher when he started solving a variety
of difficult tiling problems, such as Eternity. After Adrian and
I filed the patent, we hired Mira to look for solutions with this system
using his program, and he found thousands. Do
look at Miroslav Vicher's site, for more. For example, the following
is one of over *ten thousand* dodecagon patterns he found. He
found many squares and rectangles that eluded us, and a wide variety of
beautiful tessellations.

But none of the above links gives either of the following tessellations, both done with the same shape. This quadrilateral can tile the plane with either five-fold symmetry or six-fold symmetry.

When I made the Chaos Tiles, I found a large number of interesting tessellations based on the nonagon. Here's one of them.
