Multi-Touch Interface for Google Earth:
Google Summer of Code Blog mentions about an application created by Pawel Solyga "that allows you to control Google Earth using two finger gestures on [a] multi-touch table". I couldn't find too many details about TouchEarth, but it's an interesting application of the mostly-unknown Google Earth COM API.
I remember that one of the demos of Android (03:54), Google's mobile platform launched in November last year, showed a touch interface for a spinning globe.
