crinkle crankle walls

Saw this on facebook [ original author ] and decided to share here because it is not only interesting in general, but also smells like a permaculture design.  Specifically, seems to fit well with the idea of boundary conditions and maximizing boundary length.

Random Fact of the Day: In certain parts of Suffolk, England, you can find "wavy" brick walls. Interestingly, the design uses fewer bricks than a straight wall. A straight wall that is just one brick thick is not sturdy enough to stand alone & can be easily toppled, so they generally have a thickness of at least two or more layers of bricks, & are also reinforced at regular intervals with vertical posts serving as buttresses. But a wavy "one-brick" wall stands just fine on its own due to the arch support provided by its shape, which combines both fence & buttress. Such a structure is called a "crinkle crankle wall".

Plus look at all those microclimates, especially if the wall is running E/W.

They are also known as “forcing walls” - the little microclimate in each wave can be used to push plant zoning boundaries!  I’m trying to find if there are any general rules on “frequency and amplitude” measurements to optimise strength, has anyone actually built one??

Just for cross-reference, there is a thread with a similar idea made out of free pallets
