Last week's entry turned out to be pretty easy, apparently: it is Uluru, otherwise known as Ayer's Rock, that really big, well, rock in the middle of the Australian Outback. Also, UI 52 was identified as the Cloud Gate sculpture in Chicago's Millennium Park. Several incorrect guesses thought it was a pool of water, but a careful look at the relections reveals that the surface of the object is convex and not flat, as a pool of water would be. Anyway, congrats to the winners!
And now for this week's entry:
Where are we? Rot-13 your guesses, folks!
