Hello! Runners Map
Adidas Japan has created this innovative blog widget which visualises user created running routes using Google Street View. Joggers can plan their route on Google Maps and then view a movie of the route in Street View.
This flash introduction explains the concept and application:
The Hello! Runners website makes full use of the Google Maps for Flash API to create a unique design for the map that complements the design of the rest of the site.
