On twitter and their blogs, Daniel Ruiz Aguilera and Simon Gregg have been pattern block crazy. Daniel recently did a very cool class and a presentation about it (see more) and Simon is always breaking reality with his students and pattern blocks.

And then I got wondering about a tile with maximal dodecahedrons. I really liked the result of four 90o rotations.

Here's how I filled in the gap. I had blue rhombs where the triangles matched up, but that blurred the lines of the dodecahedrons. And I wanted it to look like it was overlapping. (On Math Toybox.)
This was a little maddening, but also fun. By the end these arrangements just made a deep kind of sense and I could see the pattern and replicate it easily - definitely not the case at the beginning. So thanks/gracias/merci to Simon and Daniel.
