Slide projector help, Keystone correction?

    Hello all,

    I have an odd question. I'm now involved in a project to put together
    a 4 screen slide show using dissolves.

    The biggest issue hitting me at this point, is that the space to put
    this in is about 4' deep.

    Given that the projector is about 1' deep, and that the mirror might
    need to be angled oddly, this is going to be fun.

    I plan to use 4 first surface mirrors and build the setup like a rear
    projection TV.

    My issue is, Keystone correction. Do you think I will be able to
    correct for keystone issues by modifying the placement of the mirror?

    Anyone ever do this before? I am going to research the lenses tonite
    and find out what is the shortest throw. Luckily my screen size is
    fairly small (will get measurements, but I think it is about 5' wide).

    I have zero equipment, so I'm going to be scrapping up a bunch of
    Kodak's from eBay and other sources, followed by a bunch of Dove X's.
    I found windows software to control one dove, so I will most likely
    lay down a track in the computer, time shift a few of the effects and
    then be good to go. I'm worried about the bounce mirror and keystone
    issues. My budget is pretty limited, which is the main reason for
    going with 35mm slide projectors over digital projection.

    Plus I've always wanted to play with a film recorder :)

    Thanks in advance.

    Well, how did it go? I would suggest getting a lens that would throw an
    image at the size you want with the distance you have without the
