Refinery 99 points us to this flickr photoset from one “unclekuntz,” a Photoshop practitioner who seems to enjoy imagining an alternate reality where giant ladies roam the earth.
The above photo illustration of Victoria’s Secret “Angel” Miranda Kerr stomping the Golden Gate runway was the only SF-set one I could find, but there are 317 photos in the set, so perhaps one of you macrophiliacs with some time on your hands can let us know if there are others?
One warning before you take on this task: as urlesque notes, the set is “just barely NSFW,” and Refinery 99 says they’re “getting a palpable vibe that this stream wasn’t created entirely devoid of prurient interests.” So, maybe not the best slideshow to page through if your boss looms behind you.
