Since that release, developers have had a chance to create some very interesting mashups using streetview, and in a recent Maps API blog post, Google's Pamela Fox highlighted some of these (3 of which are now cataloged in our directory: StreetView Adventure Game, Povo Boston, and Dual Maps):
- StreetView Adventure Game: In the spirit of the classic interactive fiction games like Zork, this demo lets you play a short game that begins with chasing a guy trying to climb out a window in San Francisco.
- DualMaps: For a given location, displays the Street View, Birds Eye View, and Google aerial map view simultaneously and lets you embed or share the result.
- Povo: A local reviews site specially for Boston. Displays street view in a lightbox for each location, and has made a Street View tour especially for the recent Boston Marathon.
And if you want more streetview mashup examples:
Also check out VegasVision, Ong Map V2 (Alpha), VPike, FlyRig, Street View Gadget, LotView, Street View SF Tour, RealBird, Glotter and a Street View Tour Gadget. And if you loved Trulia's implementation (announced on Google LatLong last week), check out this demo that shows how to angle a street view panorama towards the side of the street that a building is on. (It involves math, but don't worry, we've done it for you.)
