Brainstorming here.... Are we trying to create a three-dimensional effect? I wonder how it would work to have two screens, a foot or two apart. The screen nearest the projector would be somewhat transparent, and the second screen white. The offset of the two images would be determined by the position of the observer. (Maybe this was already invented 100 years ago.
In my luminous trike project module I used four screens of veil netting (I don't know what they call the stuff but it does remind me of an aquarium fish net.) red, green, blue, and white suspended on two boron graphite fishing poles at the different eyelets. Safety white el-wire strung along also framed the edges. Veils were slightly weigh with washes and safety pins and waved some in the gentle wind. Used an inexpensive 60w kids dvd video projector. I had my old Sony digital8 video camera on top and could monitor back in nightvision and/or special effects such as negative color imaging. I wanted to try anagraphic 3D but didn't get that far into it, though I did bring paper red/blue glasses to gift if I had. Art as an experiment can go in many directions from ones original inspiration. It was cheap, funky at best, at appropriate risk level for the playa enviroment. And it was interactive, and fun. But small so didn't attract too much attention with so many big things going on.
