Projection Surfaces

[Ivan R. Judson]

Don,

The cheapest and easiest way to get up and running is just to project onto a
painted wall.  Even fairly dark looking (20-30%) grays will work well enough
to impress most people...

  The Walltalker comes 5 foot wide and you order it in the length you need.
We use it in two nodes here at NCSA.  We have not had any problems with
erasing it, to this point.

    You all bring up good points, so I'll abandon the thought of 3 small
    bargain-basement screens.  I've considered the wallpaper route myself.
    Does anybody know just how wide this wallpaper is?  Has anybody had
    any problems with it not erasing completely after being used as
    a whiteboard?

    With our small room, our projection surface will be roughly 10',
    and I anticipate projector images of roughly 3.3' x 3.3'.  So,
    hopefully two strips of the wallpaper would do the job.  Still
    haven't made a firm decision on wallpaper though.  Other possibility
    is to just buy a 10' wide screen that pulls down over an existing
    whiteboard.
