Alternate visualizations of groups

My jaw dropped when I had a glance at this. This company (PTGrey) is making some really creative imaging products. Some of them are specifically designed for watching group behavior.

Awesome video of 3D vision (link at bottom of page)
Imagine if humans had developed with this kind of visual system from the start! I'm not a big fan of military applications for this technology, but imagine a soldier who could see in all directions at the same time...

Also check this video of tracking group movement and visualizing traces left by people.
