Among the wind cult, it’s apparently the ‘aesthetics’ of these things that titillate the senses and get their juices flowing: just knowing that they’re out there somewhere (in someone else’s backyard, not their own) gently caressing the breezes, is more than enough for starry-eyed wind worshippers.
