Half-Circle Patterns

Drag any 4x4 image to overlay it on any other.
A variety of interesting patterns results.

The images are a few of the many Latin squares that
can be formed using half-circles as entries. They are the
original form of the images in the diamond theorem that use
not half-circles, but triangular half-squares, as array entries.
