This is a variant of my Chevron Corrugation in which every other row of chevrons is reversed, i.e. pointing down instead of up. This makes the corrugation iso-area, meaning both sides look the same. It also removes the tension which causes the basic version to curl: this variant can be spread as narrow or as wide you like without curling.

Potentially, pushing individual chevrons up or down (rather than whole rows) could be used to create pixel images.

A model almost identical to this one (just the angles seem a bit different) is seen in the Paper and Stick movie by Ron Resch which shows models he designed in 1960-66.
