An interactive installation for a double projection screen at Meyerson Hall at the University of Pennsylvania. 26 sheets of laser-cut Tyvek block the entrance of the architecture school with a double perforated drapery. At night, projections come from the building and from the yard shooting at each other. The perforations on the front screen allow for light to penetrate and project on the back screen and vice versa. The party guests have the opportunity to walk between the screens and experience the colliding lights.
