If you haven't checked out Google maps in the last few weeks, you've missed the "street view" feature that was rolled out for five or six cities (including Denver).
There's a street view button on the map and it allows you to point to just about any place and click and it pops up with a 360 degree view of that point. It's pretty cool.
Now, a Web site has sprung up where people are posting unusual pictures they've found using street view: http://www.streetviewr.com/
Check it out.
