Google today added a new item to their online store - a 3D pressure sensitive mouse that makes flying or navigation inside Google Earth a breeze.

Using this mouse, users can fly through Google Earth, change directions, camera views or even work on 3D models inside Google Sketchup, a free CAD software.

Called SpaceNavigator, this mouse is compatible with most 3D software including Maya, AutoCAD and NASA World Wind, a competitor of Google Earth.

This may also catchup with architects and designers who use 3DS Max and Revit Building to create virtual walkthroughs for clients.
