Confrontation Origami Tessellation
This is one from back in August that got overlooked for a while. It's a pretty simple concept that creates a rather tangled design. The center is an offset hexagon with six triangles twisting around it. Three on the front and three on the back. A classic module. Then I added some rhombus twists off of the corners of the triangles. This is a mirror symmetry twist tessellation . The reverse side is a mirror image of the front. I don't have a crease pattern for this one. However, this pic shows how to fold the six triangles. Alternate up/down. Then add the rhombuses to the outer points.
