Reface [Portrait Sequencer] (2007: Golan Levin and Zachary Lieberman) is a surreal video mash-up that composes endless combinations of its visitors' faces. Based on the Victorian "Exquisite Corpse" parlor game, the Reface installation records and dynamically remixes brief video slices of its viewers' mouths, eyes and brows.
Reface uses face-tracking techniques to allow automatic alignment and segmentation of its participants' faces. As a result, visitors to the project can move around freely in front of the display without worrying about lining up their face for the system's camera. The video clips recorded by the project are "edited" by the participants' own eye blinks. Blinking also triggers the display to advance to the next set of face combinations.
Through interactions with an image wholly constructed from its own history of being viewed, Reface makes possible a new form of inventive play with one's own appearance and identity. The resulting kinetic portraiture blends the personalities and genetic traits of its visitors to create a "generative group portrait" of the people in the project's locale.
This video documents the interactive "Scrapple" installation at the Ars Electronica Center, Linz, 2005.
Scrapple (2005: Golan Levin) is an audiovisual installation in which everyday objects placed on a table are interpreted as sound-producing marks in an “active score.” The Scrapple system scans a table surface as if it were a kind of music notation, producing music in real-time from any objects lying there. The installation makes use of a variety of playful forms; in particular, long flexible curves allow for the creation of variable melodies, while an assemblage of cloth shapes, small objects and wind-up toys yields ever-changing rhythms. Video projections on the Scrapple table transform the surface into a simple augmented reality, in which the objects placed by users are elaborated through luminous and explanatory graphics. The 3-meter long table produces a 4-second audio loop, allowing participants to experiment freely with tangible, interactive audiovisual composition. In the Scrapple installation, the table is the score.
