StreetCities is a nifty new service that lets you embed a Google Maps street view and map in a blog or website.
I particularly like the ability to switch between the Street View and the Map. I think I might be using StreetCities a lot in the now regular Fridays Maps Fun posts to show some of the more interesting street views found on Google Maps.
StreetCities' views are very easy to set up. It is just a question of finding your location on a Google Map (there is a handy geo-coder search to guide you) and then defining your map and layout options.
