Well here is a very cool site that you must try especially if you have a smart phone.

This site allows you to create cool Augmented reality tags,videos and other 3d stuffs on ordinary Google maps that you see. It is a Location Based Tracking System. This means that if you point your smartphone camera around you then you can see floating animations and sounds depicting where exactly is a given building and its route.
I had tried a bit on this and created a channel in Junaio to make a Location Based Tracking System. If you have a smartphone and are staying in UT Arlington, you can use my channel to find out where different buildings are in the campus by just moving your phone around you. My Channel can be found as AbhinavAR in its list of channels.
