This morning Google gave their 2D maps an incredible realworld addition. Its a street-view, that in certain cities, will let you get a street side view of the area you are currently in. This is not just a static, A9-style image. It will also let you move along the street in a smooth manner and even more amazing it will let you change your angle and continue moving that way.
Right now, only five cities are available: Denver, Las Vegas, Miami, New York, and San Francisco.
Try it for yourself, here is Las Vegas.
