This corrugation is exactly what it says on the tin: blintzed bird bases tiled side by side. Large tilings have a slight tendency towards curling, but it can be overcome by folding all creases sharp and applying a little force in the direction opposite of the curl. Folded the right size, this corrugation could be used as an egg carton or as a set of small containers for screws, nails, candy or other small objects.
Model designed and folded by me. Later, I found out that other people had come up with the same design independently, namely Evan Zodl (who made an interesting curved version called S³) and Toshikazu Kawasaki (his model is called Rhododendron).
