Google just released the API for the street view functionality of maps.
I made this example Google gadget that uses the new API that displays a few historic landmarks in Philadelphia to illustrate some of the gadget potential…
The gadget takes advantage of the “simple street view panorama” example provided with the API release. There are several demo examples given and the possibilities are endless.
Can you say real estate? Real estate people can do tons with this.

this is really cool! i love the panoramic scrolling! I hope they cover some landmarks in Dublin like the GPO and Four Courts, that would be cool.
