The Neutrino Video Project
From IRC Improv Wiki
The Neutrino Video Project debuted at a Cagematch vs. Mother. Neutrino had worked out an ingenious system of camera teams and runners to tape a Harold and have it play as they were continuing to tape the show the audience was watching. The effect was hit home when Mother members Jason Mantzoukas and Jesse Falcon did walk-thrus during the video. The group went on to refine the format and made it less beholding to strict Harold structure.
