It's called the 'SpaceNavigator' and it looks like a massive price breakthrough for this class of device (previously they retailed for around £200).

Basically it is an input device used in the opposite hand to your mouse hand. It is used with 3D design software to rotate and zoom a 3D model or navigate a 3D environment.

It is currently windows XP and USB only. It looks like 3Dconnection is now supporting the popular Google 3D applications Sketchup and Google Earth. A full list of supported applications can be found here:
