In March 2011, Lipstate showed ARTIFACT, a multimedia installation exploring process, rescission, and artifact in film and sound, at Splatterpool Artspace in Brooklyn. She collaborated with Chris Habib to create an interactive personal echo chamber fitted with a cassette player running one pre-recorded tape loop. Each time a participant engages the echo chamber, a switch activates an erase head atop the structure deleting a portion of the audio randomly from the loop. As more people visit the chamber, more silence is restored to the tape.
