Las Vegas Travelog: Sahara, Stratosphere
Apparently a roller-coaster. After coming out of the building hole, it immediately dips into the ground thru a subway-entrance like hole, coming up to encounter a loop, then culminates in reaching a vertical pinnacle, where its kinetic energy decreases and potential energy increases till it is motionless, then gravity takes its toll and the whole scenario falls back into a reverse. Common sense says that it couldn't ride gravity all the way back to its starting hole. Somewhere along the way, humans must have pushed it.
Its website [ http://www.stratospherehotel.com/ ] bills: “At 1,149 feet [350.2 meters], the Stratosphere Tower is the tallest freestanding observation tower in the United States and the tallest building west of the Mississippi River”.
Atop this tech belvedere is a rotating restaurant, so that, as you engage in the pleasurable activity of subsistence, you can also enjoy a view of those beneath you. This belvedere also hosts a roller coaster, the highest roller coaster in the world, bound to safely fright.
Also of interest in the photo is that it uses a bunch of fake flags to give a air of internationality. Suppose one of its fakes looks similar to the flag of country X, then country X can sue Stratosphere's ass off in America.
