Does it regenerate? ;)

It doesn't look like it as someone would have had to do a lot of work. The shadows all line up, the fixtures are different angles, and a couple of other details.

Not to say it couldn't be done. I was thinking more of urinals in the same basic setup, but with much more original space that the Photoshopper removed.

Well, I've really studied the image. There are two distinct light sources - the one that lights the left urinal is at a much lower angle than the one that lights the right urinal, which is made obvious by the line of capping tiles, and shadows cast into the urinals themselves. The lights are at 90 degrees to each other, and all other shadows are consistent with this placement.

Although one could fake it, the probability of someone having the time or motivation to do so is improbable, so I'm going with the E=mc2 theory.
