just stumbled over the work of scott snibbe who makes marvellous "expanded cinema" type screen interactions. his site has some excellent photos of works …for example:
Compliant creates a projected screen of “soft light”. As visitors walk into the field of the projected screen, the shadows of their bodies cause the screen to be distorted and pushed away, as if the screen were a rubber sheet. The physical bodies of the viewers become the dominant force in the relationship with the screen, distorting it, pushing it out of its alignment, or completely chasing it out of view. Multiple viewers can impose on the screen from all angles and hasten its disappearance. This give-and-take relationship with the screen also evokes cinema more directly, by recalling the slapstick comedy of Charlie Chaplin endlessly chasing his hat in The Tramp.
