is an international initiative of the geological surveys of the world which is taking the data from the individual surveys and combining their data into a consistent format to produce the first digital geological map of the world.
There are previews of the insanely large sample files on the press page
. There is an interactive thingy here
. It only works in IE and (2 < Firefox < 3). The default image it brings up is just the surface of the Earth, ala Google Earth, but you can add layers of geological information, at the world or political unit level, with the "add layers" button. From one planetary geology course (Moons for Goons) twenty years ago this looks pretty cool, but I will defer to the geologists among us.
