Roomograph is an inflatable, room-scaled installation made from a combination of clear and photosensitive materials. When lit, it looks like a puffy space with places to sit or lay. As people interact with it, Roomograph works like a photogram, its photosensitive surfaces are blocked from light as occupants linger. When the lights go out, occupants see their outlines as shadows on a glowing field. Roomograph is comprised of two forms, one occupied at the perimeter and one at the center, encouraging individual and group experiences respectively. When the lights are out, the previously illuminated/ inflated form is displaced by its counterpart. During this shifting, the glowing portions will be all a visitor sees and occupants will witness their shadowy trace, as it becomes incorporated into the architecture—until there is no way to distinguish between the body and the building.
