This tessellated pattern is the result.
This super-pinwheel (a pinwheel made of pinwheels) is the result.
This is not a tessellation because the white shape in the center doesn't match the other shapes.
Yes it does.
This is a strange shape. Sometimes it reminds me of cats, sometimes frogs, sometimes lobsters, sometimes aliens off of a space ship.
I don't know that I would actually use it for anything; but the steps I used to discover this tessellating shape could be repeated with two different starting blocks and I might find something I truly love.
