Toward the left of the composition, a large video diptych, showing live footage of us, the viewers, mixed and processed with pre-recorded video. The live video is picked up from two cameras hidden within the mural wall. The footage from each camera is displayed in a different half of the video diptych, mixing with pre-recorded video. If no viewers are present within a camera's range, pre-recorded video plays in that half of the diptych instead.
The sample below is a recorded version of actual real-time mixing of the various videos. Initially, pre-recorded video plays in both windows. Then a man enters the left window and is mixed in real-time with the video. A moment later, a child enters the right window and is mixed in that window. After a few moments, both leave and both windows revert to playing the pre-recorded video.
