Found a really cool Google Maps hack today. It shows the map and satellite images superimposed over one another. It is quite cool for locating stuff on the aerial shots. You can adjust the transparency, and can swap which is on top, either the satellite or map images. Just need to hack this a little more so you can enter an address to jump to, instead of the pre-defined city list. It does provide a way to enter latitude/longitude coordinates, but I really don't those all that well.
