At CES a few years ago when CDV was the buzzword, Philips had a bunch
of CDV machines connected to a beast called a Vidiwall.  It was a four
by four array of flat screens.  There were no seams between the
screens, so it made a pretty impressive big picture.

Several pictures could be displayed in differing widths by combining
several of the screens.  It was controlled from a computer terminal of
some sort.  I couldn't get close enough to see exactly what was
involved, but the operator would work at the terminal and signal other
workers to cue up discs in their players.

It looked much better than any of the setups I've seen made from
ordinary monitors, but we were in the dark (I don't know how bright
it's be in other situations), and I don't know whether Philips sells
them or just uses them internally (it had their logo on it, so I
suppose they made it).
