We've all seen how cool Google maps are.  There are a few sites making interesting use of these maps (as mentioned on a google blog).   One interesting one is Google Sightseeing.  Their tagline is: Why bother seeing the world for real?

It's really pretty interesting.  There are lots of visible landmarks from the maps.  For example, you can see things such as: stadiums, landmarks, airports, etc.

I filed this under software...you know cause it's Google.  It's a stretch, but it is what it is.
