This is the interior of the Luxor Hotel and Casino in Las Vegas, Nevada. It's an enormous black glass and steel pyramid. The photo is of King Tut's statue. You can see the shape of the pyramid on the ceiling above. Too bad I didn't know of the project before we left Las Vegas, otherwise I would have done an outside shot as well!
Anyone else want to play? Just a post of photo of a pyramid-shaped object and link back to Lulu's site. She's going to post them all in a collage.
