Propellers Tessellation (long variant)
This tessellation is closely related to my Square Interlace Tessellation. Grid is 8×8 per molecule. Here you can see the variant with long propeller blades. I will publish pictures of short-blade variant shortly.
Designed and folded by me from a single sheet of black Khepera paper.
This image was scanned rather than photographed. For this particular tessellation, I found the scan much better than the photograph: lighting is very uniform and the scanner was able to reproduce the textured black color of the model much better than my photo camera could.
