Conference Call was an interactive audio/video game installed in three adjacent private phone call rooms in the co-working space TechArtista. In each room I installed a camera, a video monitor, a microphone, and a speaker. For each room, the feed from the video camera was shown in the second room, and the feed from the microphone was heard in the third room. The effect was that the person you saw on the monitor was not the person you were hearing. Likewise, one person could see you and a different person could hear you.
Players had to figure out a way to effectively communicate with each other.
