Most of my film work is expanded cinema, with one or two projected images backdropping the sound artist, on a flat wall or screen. This is usually the case with a venue. But I have projected loops in a host of settings, sometimes a textured wall or a fireproof cabinet, or a sheet in the woods (powered by a generator). Where I have some modicum of control, I manipulate the space to give the greatest depth to the films. I find that fracturing the image through different surface planes "opens up" the loops, some of which have contour and therefore have some range of focus. Table top projection lends itself to this kind of improvisation and chance design.
