Turn your phone into an audiovisual beat machine/comedy routine. You start by recording clips of you and your friends making odd faces and noises. CamBox cuts them down to just a few frames, clipping the accompanying audio into a quick percussive blast, and then creates a thumbnail for each. Tap out a beat on the thumbnails, hit record, and the app spits out a hilarious beatbox video.
WIRED Use front or rear camera. You make the noises, it makes the clips.
TIRED Saves at lo-res.
