Tour Builder is a cool web tool that allows users to create narrative stories using text, graphics, pictures, videos and Google Maps.Tour Builder lets you pick the locations right on the map, add in photos, text, and video, and then share your creation. Currently, Tour builder is still in beta version and it requires the Google Earth plugin which is only available for Windows and Mac OS X 10.6+.
Google explained the idea behind Tour builder saying that :
We originally created Tour Builder to give veterans a way to record all the places that military service has taken them, and preserve their stories and memories as a legacy for their families. But we also thought it could be a useful tool for anyone with a story to tell, so we made it available to everyone.
