Well, basically, you have three choices, rear projected, front  
projected, or monitor.  You can probably imagine the advantages or  
disadvantages of the projected images.  Unless you have really large  
images or irregularly shaped screens in mind, I would recommend  
considering large monitors.  It makes everything so much easier.  A  
42" monitor and a small computer can be gotten for under 2K for each  
monitor/computer set.  If you are going up to 50", then you can get  
the whole setup for well under 4K.  You don't have all the logistical  
hassles of where to mount projectors, the image is going to be a  
zillion times brighter (unless you go for some really monstrous  
projection system).   There are systems for tiling monitors that I  
don't know much about, but they are very expensive.

I see you want to project on the floors also, so you could do a  
hybrid of monitors and projection.

The CAVE systems are all about interactivity and 3-d ness, and that  
is a whole other set of issues, and I don't think that they can  
fairly be called "poor man's" approaches, since most of them are like  
millions of dollars.  I don't know about the Carnegie Mellon version,  
any more pointers on that?
