Google has added a very cool new feature to their Maps application called "Street View." It is currently only located in a few large urban areas: San Francisco, Miami, Las Vegas, Denver and New York. You position a gold human icon onto blue outlined area of a map and then zoom in to see a panaromic street level view. You can turn around 360 degrees and click on the directional arrows to move along the streets. Use the - and + keys to zoom in and out.
There is a new site called Streetviewr where you can view and post unusual photos or pictures of famous sites. Google uses a van equipped with cameras. It must have a very fast shutter, but some images still get distorted.
Here is a goofy video Google produced to promote Street View:

Kind of 1984'ish having that camera watching you!
Here is a huge list of Google Street View sightings!
