A museum in the basement contained a simulated King Tut's Tomb and treasure until 2008, when it was donated to a museum. Indoors, the motif continued, at least until a massive overhaul gutted most of the Egyptian elements. The Strip monorail cuts in front of it, so the view is more obstructed, but probably fun for monorail riders.
At one time, supposedly, it projected the word 'Luxor' onto the obelisk in front of it from light beams in its eyes - although we've never actually seen that. The Sphinx is 110 feet tall, a full two stories taller than the original.
