Narrow Bridges Origami Tessellation
It's just a bizarre crease pattern that was not easy to fold. The first time didn't work out. The second try did.
It backlights very nicely. There's a lot going on in there.
You can see the open back hexes dominating the front of the design. There are large triangles right off of those.
The regular hex twists land on the rear. As do some triangles which are natural to the grid. I didn't see those triangles at first. When I finally did, it all came together.
Still, I'm pleased with design. It's somewhat different than any others I've come across in my searches.
The rear backlit is first. I'ts more interesting in my opinion.
The front backlit is the second photo.
