Communicative Deviations

The best place to hold this little installation is either in my classroom or 'art gallery 3'; I discussed this with my teacher of course. What I am looking for is a white background to record the effect of light with cellophane, so either of these places would work, as the classroom has the option of a white projector screen/movable tack-board in front of the windows, and the gallery is painted white. I'll still need to get hooks for hanging and cotton balls for filling my shower caps to make fake clouds, but that's all up for speculation still. Hopefully I'll get it hung soon, one way or the other, take some pictures, and then take it down, since this is a very 'temporary' installation.
