Dancing Boxes Tessellation
This tessellation is comprised of rectangles twisted around large hexagons. On the reverse side there are some possible triangles. I opted not to flatten them.
I toyed with the flattening, but wasn't into it.
I think not flattening it rendered a nicer finished product.
For some reason I have a particular penchant for using rectangles in origami tessellations. I couldn't say why.
