Thanks for all the comments!

Many interesting guesses. :)

Tim: Tracking the camera frame by frame would not just take a lot of
time, it would be practically impossible. Interpolation couldn't be used
to speed up the process, since the camera shakes quite a lot from one
frame to the next. So that's not how I did it.

Flu: The camera jiggle was not added later. That's my shaking hand
alright... :P

Apache: No radiosity was used. But several light_sources with
area_light.

An yes, the hologram projector base IS raytraced for the record - not
just the globe... :)

Okay, on to the point. Some months ago I found a program on the net
called Icarus, which is used to track camera motion. I didn't look into
it back then, but a few days ago I gave it a try, and this animation is
the first usable result (after lots of non-usable results). The program
was freeware for non-commercial use.

Unfortunately I've noticed that in the mean time, it's no longer
available for download. It seems they don't want it to be free anymore.
It used to be here: http://aig.cs.man.ac.uk/icarus/

Pity huh?

Hm. But you know that we'd expected you to have
some own approach to that... :-)

Probably using camera-tracking software like Icarus (Freeware) or boujou

Extreme coolness...

I've been thinking about challenging the great POVers of the world to do
something like this for a while now... But I figured my challenge would just
get ignored. I was thinking more like putting a solid object into a
real-world still image (preferably including the author him/her-self ;-) and
making it look like it's actually real... (But this is still very
impressive!) Oh, yeah, and I'd try it myself, except that I don't have a
digital camera :-/

Andrew.
