One-handed Clapperboard

Introducing the World's First One-Handed Clapper. Humanity has been clapping with two hands since time immemorial, but that changes today! Alfred Hitchcock, Federico Fellini, Steven Spielberg - all clapped with two hands, but you don't have to. This device has interchangeable movie title plates. It houses a dual rotary counter system to keep track of Scenes and Takes. No more messy chalk or markers, everything is right there in cold hard plastic. The white tongue shoots out to let your camera capture the visual queue. The blade makes a clapping sound that you can use to sync audio and video. Hold the camera in one hand and clap with the other. Put it in your pocket. Uses a switchblade mechanism for deployment and retraction. The case doubles as a gray card for color corrections.
