Found it! and its way more complicated.
The shot i mentioned on the "Person of Interest" seems to actually be slow motion video. Closer examination reveals its not a still frame at all.
I found the actual effect i was seeking on the Film Riot site.
They used a computerized motion control rig from Kessler. And some spiffy software...
Very cool but unfortunately out of my budget for now.
If you want to see how they did it check out the episode - The Frozen in time Effect!
