Activate satellite view in Google Maps and head to the Las Vegas strip, and you'll see it: a strange smattering of Y-shaped buildings. Their blueprints put gambling at the center of everything, funneling visitors past slot machines and card tables whether they're en route to a show, their room, a restaurant, or a retail shop. For years, the casino floor was where Vegas resorts made most of their money, and the Y was devilishly good at monetizing it. The Westgate Las Vegas Resort and Casino was the first megacasino to feature the design--a bit of trivia that Mark Waltrip, Westgate Resort's chief operating officer, relays with a mixture of pride and irony. Y-shaped buildings have their issues, after all.
