HELP!

Here is my request for technical advice - see next post for answers..

I’m working on a project (Virtual Streeet Corners) that requires a “life size screen” meaning about 5’ or 6 ‘ high screen or monitor, and since the cost is prohibitive I’m wondering if anyone knows a cheaper way to do it, such as joining or stacking monitors. I want it to be viewed in a window during the day, so a projector won’t work.

What software do you use so that you can make multiple screens show one image, that will work in portrait fashion as opposed to landscape.

How do you eliminate the casing so you can butt the screens right next to each other , eliminating the space between the screens?

Alternatively -- if all else fails -- does anyone have a screen for rear projection?
