3DConnexion, exhibiting at MacWorld Expo this week, have just added the Mac driver for their SpaceNavigator 3D controller to the download area of their site. It’s an 0.1 beta, but very real. Install it, and the SpaceNavigator will light up with its familiar blue hue when you restart the Mac — a wonderful sight to behold:-)
SketchUp 6 for the Mac now works with it, and there are also drivers for Maya (which I haven’t tested). No word yet as to when Google Earth support arrives.
