Google Earth has gone indoors in 3D- just another level of real-world linkage across local to global scales.  With Google Art Project- you can use Google Streetview to go into museum galleries and browse art in high resolution: http://www.googleartproject.com.

This has really got me thinking: can we get our 3D ground scanning methods to bring us into the forest in 3D? I love the idea- can we make it happen?
