That is so cool! Ostensibly, it looks as though they are simply commenting on the creation of a wind pattern. I wonder, though, if there isn't some other meaning. Are they telling us something technical?
BTW, I just returned from a trip and I saw windmills that were in the process of being put together. Just for context, the blades alone are the length of eight cars!

They are quite amazing (their size alone is awesome) and their installation is bringing about good things in the local economies where they are being put up.
