Only at Nasa could we simulate an entire control tower with 12 CRT RP setups (not blended, each RP screen is one pane of a "control tower window" with appropriate frames.)
Here's the site: http://www.aviationsystemsdivision.arc.nasa.gov/facilities/ffc/index.html (Pics under Multimedia section.)

Nice, I'll take a 3 panel unit so I can game widescreen.

Why are they mounting them upside down?
It must be much easier to service them if they are floor oriented.

Mirrors fold the light path and shorten the "dead" volume of the building.

Yeah, mirrors and folded optics for shorter throws and smaller footprint are correct. But, that wasn't really David's question.
The rendering still makes it appear as if the projectors (which do appear to be Marquee-ish) are all mounted upside down. That would indeed make maintenance a total pain in the ass and require complete dismounting - and for what? There must be a reason. Is the keystone range different on the Marquee for positive/negative?

Well, here's the higher-rez image and it does indeed look like they are upside down. (not embedded because its' pretty big.)
http://www.aviationsystemsdivision.arc.nasa.gov/multimedia/ffc/images/concept_towercab_high.jpg
Since this is just a computer rendering, I'm sure that the CAD guy was given a model (or dimensions and a photograph) and told to put the things pointed at the mirror.

CAD guys are crazy - I would not take anything away from the rendering.

Yeah, probably more of an illustration, with some details left to the CAD jockey's imagination. I can hear it now: "I'll email you a couple PDF's. Here's a drawing with dimensions. Put some computers and monitors in the space... Oh, and here's a basic drawing of the projection setup. Put it all together and shoot us a rendering so we have something to show people."

There's no good reason to mount them upside-down. You could reverse the scan so you could mount it right-side-up and still get the pic you wanted.

Yeah but do THEY know that? Wonder if the bothered to read the manual. 
It looks like the projectors are on a pivot point maybe? They could jsut flip over and be serviced

Guys!
There are much bigger rigs out there, Los Alamos Labs has a Cave type system using 24 stereo DLPs onto the floor, three walls and the ceiling:
http://library.lanl.gov/cgi-bin/getfile?28-18.pdf
Scroll down towards the bottom. I have worked there on five different occasions but not on that project. The security on the Los Alamos campus is the definition of "terse".

Iowa State University Virtual Reality Applications Center's (VRAC) C6 cave is equally impressive. 10'x10'x10', it uses 24!!! Sony SXRD projectors to create a stereo 4k x 4k image on each of all six sides of the cube. You stand on a 2000-pound piece of plexiglass that's both floor and projection screen. The C6 was originally set up with 909's, but was moved to the Sony SXRD's last summer in a huge retrofit.
http://www.vrac.iastate.edu/c6.php
My buddy designed the enclosure:
I did some work for Mechdyne - the guys that set this system up - back in the CRT days. They do some pretty kick-ass work. I'd still be working for them, but I couldn't deal with all the travel.
