Hacking Google Maps
Here are some Bookmarklets for doing various things with Google Maps, like panning the map and having it auto trace the route between 2 locations.
There are 3 variations of the route tracing bookmarklet. The first one just moves the map. The 2nd actually moves the marker along the route, and the third loads an image of a person and moves it along the route.
Some really neat stuff and more should be coming out soon.
