Watch the lady who has her arm in the air.. you can see "around" her arm as the camera pivots.

I agree that doing it with flat pics looks impressive but this isn't done like that.

you can pick up N90s' on the cheap these days which is what they used on the original Matrix array...

The person walking while everything else is still is comped in front of the frozen scene using greenscreen.

Some of these frozen scenes are far enough beyond the point the camera is pivoting around to have been possible by stitching still images together, but it looks like they were mostly shot with camera arrays anyway.

There's a pretty extensive discussion of the effect in this thread:

Here's a great article and podcast interview about how Mark Ruff achieves this effect with near realtime results using arrays of Canon 10D cameras, each linked to their own macmini:

It looks like two videos where the 1st is frozen because look at the guy running, he is consistantly blurred.

can be used to morph frames together.

PRetty killer results can be seen on their web site.
