Especially when you combine it with computer games. A team at UCSD are experimenting with using a hacked Kinect to rapidly create 3D scans of archaeological sites. This technology can’t come fast enough for me, and I think anybody who has ever painstakingly mapped a cluster of rocks with pencil and clipboard, on the off chance that they might be significant*, would agree.
*It’s amazing how often what appears on the surface to be a deliberate stone ring will prove, upon excavation, to be just a random bunch of rocks. Sometimes the human brain is a little too good at seeing patterns.
