In seeing these constructions afresh, apart from naming conventions or economic functions or intellectual cliches, part of what struck me was that the objects and scenes in front of me looked just as much like futuristic or alien products as they did like human artifacts of the past or present, with their own kind of mystery, power, and beauty. But another reason for my series title was that when I consider the functions of some of these structures, and the effects of their uses, I can’t help but think of ways in which we human beings are indeed a kind of alien race on this planet.
