       Could be a single light akin to those multi-LED white light arrays.   
      
       With the odd dispersion pattern of LED lights, a wall's worth of them   
   could illuminate the scene very interestingly especially if driven by the   
   same software that runs a LED billboard..   
       They'd still need some kind of back-lighting for contrast with the main   
   characters and a bit of overhead lighting to give a decent level of ambient   
   light.   
      
       Maybe it's a tri-color dynamic LED laser illumination.  Sharp contrast,   
   nearly infinite shaping capacity, superb distance spot-lighting, but highly   
   vulnerable to flicker and it has to be ran through cross-polarizing LCD   
   filters to dim it decently.  Shadowing effects would be highly undesirable   
   (edges would be tri-colored and flicker with movement) and you'd have to   
   deal with three off-focus shadows in dimmer versions of the main colors.   
      
       It could be a computer-controlled high-frequency burst phase strobe   
   light field.  The bursting effect has a sine-pulse shaped intensity   
   variation to not only illuminate the scene, but also convert all in-field   
   objects into relief maps suitable for rendering in 2+1/2 dimension 3D   
   effect.  Of course, this requires a digital camera array with a fast RAID   
   hard drive server and a few gigabytes of RAM to buffer the influx of raw   
   images to process.  The nifty thing about this camera-lighting-sync   
   technique is that virtual 3D lighting can be introduced at any angle and any   
   number of virtual 3D lights can relight the scene without distinctly   
   requiring a full-CGI rendering system.  More on the basic prototypes here...
