This is neat and useful. One of my clients bought one, they're about $100k USD. It's not really a camera so much as a software engine paired with an off the shelf high frame rate HD camera. Anyway it lets you do neat things like visualize the sources of vibration. You can also see people's heart rate by looking at the pulse in their face.
