Nice microscopic imager 3Ds. It's very cool to be able to wander around some of these micro landscapes as if you were a couple of mm tall. If you get time you should check out some of horton's rat threads, take a look at some of the many 3D images he and others have posted. I know you'll be more than impressed.
You'll find some cool micro terrain 3D images on my site along with some x-eyed MGS Mars Orbiter Camera stereo images:

The geo wall set up is very interesting, I wouldn't mind giving a presentation using this technology myself.
