Update: Thanks to cowens and others who
informed us that this is actually an absolutely massive piece of
land art called http://www.archipedia.org/landscape/desertbreath desert
breath. Click through for some images and a way better
description than I gave it!

What on earth is the purpose of
this massive spiral in the Egyptian desert?

It appears to be made from near-perfect circles scooped from the
sand, which decrease in size toward the centre of the spiral -
where there is a much larger circular trench.

Whatever the spiral’s purpose actually is, it must have taken a
serious amount of effort to put here.
