This is an open back hexagon twist based tessellation that uses short/wide triangle shapes to create some interesting geometry in the spaces between the repetitions. 

The central triangle shapes are essentially a single edge of an open back hex twist. 

I had a crease pattern, but I don't know what I did with it. 

Will have to see if I can find it to add at a later date. 

I really like the movement on this particular design. It almost feels like it's in motion, even though it's just a still piece of paper. 

Coming up with it was pretty ordinary. Just decided to combine some familiar shapes in a different way.
