I wasn't sure what to make of these sculptures when I first saw them, only that they were strangely appealing, almost other-worldly.
Thinking about it since taking the photos (and I know nothing of the original motivations of the sculptor Jens-Flemming Sorensen) it struck me recently that, combined, they become suggestive of Humanity's exploding population, leading to over-crowding of our planet and our desire to reach for the stars and other places to call home.
