Math at the Beach

This is a collection of things that can be used to mathematically enhance your sand castle designs. It comes in five parts:

1. Rollers: to add texture to the sand.
2. Mathematical shape molds: Your favorite 3D shapes in sand.
3. Polygon Cookie Cutters: For all your polygon needs.
4. Bucket molds
5. The sigil.

Everything is made with math to play with math. All of my design work is done with Mathematica. So everything is created from formulas as parametric plots.

It has been an interesting summer of design and redesign. We started with the notion of flat panels to add interesting patters to castle walls. But we had several issues with the panels. These issues included the printer not printing properly (the panels had a tendency to warp), and not cutting into the sand well enough. So we moved to the idea of the rollers.

Rollers: The hole in the middle of each roller is designed so that the roller will slide onto a paint roller handle. You will find a large
