Nine Nonagons: Backlit

This is my entry for the tessellation-group's "Nine" challenge for September.

 

Folded from a 60-120-60-120 rhombus of white kami, cut (ripped actually) from a 10" square.

 

As the title suggests, it has nine nonagonal twists which are arranged in a 3 x 3 rhombus shape.

 

This was folded from a specially designed gridding system, and all of the angles in the tessellation are multiples of 20 degrees.
