Check out an application which integrates Google Maps "Street View" technology to give you a real look at the Las Vegas Strip. It features a smart user interface design that I'm sure will be adopted into more than just travel websites. User simply click a hotel parcel on the map (ie: map overlay) to your left... then get the view from that location on the right. For additional features, check out the instructions listed at the Vegas Hotel Hunt website. Also check out MapJack for another integration example of Google Maps "Street View" technology.
