HELP!

I'm stuck in an hourglass!!!

While visiting my friend in Chiang Mai (northern Thailand), we went to the art museum. They had a really fun exhibit of 3-D art. There were lions jumping off the wall, waterfalls with rickety bridges to "walk across," mountains to sled down, dinosaurs flying overhead, lava flowing underfoot, and lots of other pictures. Everything was painted on the floor/walls to make the pictures look 3-D when taken from the right angle.
