Castellations

Beach Inspirations
------

A sandy beach is essentially an infinite, maleable, instantly-erasable, reshape-able plane; a whiteboard on which patterns can be created, modified, erased, and washed away. Relationships can be formed and destroyed with a shovel, a bucket, a hand, or a wave. And the space available for exploration is vast, practically infinite.

A beach can naturally be filled with dunes, with children, with sun. But can math fill a beach? Can small shapes, ones we can hold in the palm of our hands, be made to cover wide sandy planes? Let's find out together by exploring **tessellations**.

The tessellation is a type of infinite pattern that completely covers a plane in one or more shapes. The squares of a checkerboard, carried out to infinity, are one basic type of tessellation, as are the cells of a honeycomb. These patterns, made of basic shapes (squares and hexagons, respectively), can both be carried out to infinitely, filling all the space on a plane, much as t
