Flagstone Origami Tessellation
I found the crease pattern on Robin Scholz's flickr page. https://www.flickr.com/photos/praisepratajev/6055165461/in/album-72157627404378271/
It was a huge pain to fold, but in a good way. It's large hexagons surrounded by very closely packed rhombus twists.
After having tried various methods for folding the complete pattern, I discovered the path of least resistance.
At first I tried doing one molecule and then doing another whole molecule. That didn't work very well. Then I tried doing all the hexagons and attempting to fill in the rhombuses. That wasn't successful either.
I just kinda messed with the edges until I got something kind of acceptable. I probably should've trimmed the paper as the crease pattern suggested, but it didn't seem to be a necessity.
The unlit finished design is pretty mundane. But when you light it up, it's pretty spectacular.
