I have seen this NIN video and while I am not a big fan of the band
("closer" gave me nightmares and I didn't even see the unedited
version) it is very neat. It's been a while since I saw this last, so
I'm going from memory of viewing it.
Without having the specifics from the production company, I can tell
you how it "might" be done. The pin frame and pins at least, and quite
possibly everything on the desk, are computer models. Though you could
composite the desk scenes from regular 2-d footage obtained from a
motion-control camera crane if you wanted to cut down on the animation
load.
The footage of Trent screaming his lyrics was turned into data for
moving the pins around using a displacement map. How they derived the
map I don't know for sure, but he could have been mocapped
(motion-captured) by shooting him signing into a mirror while wearing a
lot of little dots on his face. The dots are tracked to derive motion
data to drive a 3-d scanned model of Trent's head. The motion data
drives the displacement map which drives the model of the pins as if a
guy was really pushing his face against it and there you go. They might
have skipped making a scanned model of his head and derived everything
from the mocap footage.
You can cheat this effect a couple ways. One clever bit would be to
simply grayscale the Trent footage and use a variation of something
like the Adobe card dance plug-in in A.E. and the grayscale map to
animate variable pins. But to get the grayscale to work properly would
take soem extra manipulations first, and some tricky lighting to keep
showing the contours.
If you were, say, spending a life sentence in prison with nothing but
time on your hands, you could stop-motion animate the pinboard by
looking at a composite of the footage and the pin board and manually
moving all the pins for each frame. At which point your condition would
tend to resemble Trent's:-)
