It's unusual for me in that it's not a flat design. The triangles have dimension.
It is possible to flatten them into irregular triangles on the back, but I chose to keep them active on the z axis.
I remember when I was first learning origami, I was into a John Montroll book about stars. He had a design for a star just like the one repeated here. Many of his books really inspired me and taught me a lot. So This particular design has some sentimental value.
It's interesting to think about how various styles of origami converge and relate to create new designs and possibilities.
