Designer: Meenakshi Mukerji

Instructions: Here. Also, check out Assembly Guide. Instructions also found in the book Ornamental Origami: Exploring 3D Geometric Designs (2008, 154 pages) by Meenakshi Mukerji. To get started with models like these, check out How to Make Intersecting Plane Models.

Comments: Individual modules are very simple. Assembly requires patience and visualization. Took me about 4 to 6 hours to finish. The overall design is 'nine intersecting stars', one star per color. Each star is in a plane -- notice the star made by brown paper in the picture.
