This is a really cool mashup of real estate videos from YouTube and Google Maps. In essence the site maps real estate videos of properties that have been uploaded to YouTube.
It is possible to search for properties by location and the results are shown on the map and listed in the map side-bar. Each map marker contains a link to view the video which, when clicked, loads the video below the map.
The site also shows videos that have been uploaded to Vimeo, Blip.tv, WellcomeMat or Yahoo.
