Projection Surfaces

[Mark D. Johnson]

Don,
    We at USC are going the wallpaper route (WallTalker) to save space as
well as money.  The three projectors that we are going to use have 2k lumens
each and should give a very sharp picture.   This will be similar to ANL's
setup we saw in September.  I feel that having one screen with the 2 or 3
projectors merged together will give a cleaner appearance and keep the eye
from focusing on one particular screen.
