This is an idea that I had a while back, but it seemed next to impossible to actually execute. 

While it's not a very clean fold, it's satisfying to have done it. Slightly better paper might have yielded a somewhat neater finished product. 

It's a very small, very densely structured design. 

It's rhombus flowers, like the classic just rhombii flower flagstone. However, it's the tiny rhombuses natural to the grid. 

Collapsed hexagons are at the center of each 'flower'. Small triangles negotiate the spaces in-between.

Crease pattern is included below.
