Chevron corrugation — top-down view
New corrugation, designed and folded by Michał Kosmulski. Chevrons from one row limit the mobility of those from other rows which causes the corrugation to curl when you try to expand it. This can be worked around by reversing the direction of some molecules. This can create regular or irregular patterns and can probably be used to create pixel images as well. I’ll post some examples soon.
Since the pattern is very simple yet elegant, it may already have been invented before. Please comment and let me know if you’ve seen this corrugation published elsewhere. Update: I learned that Daniel Kwan folded this pattern before, inspired by a similar model by Charles Hoberman (details here).
