There is a new invention for the stressed out or angry individual: the Screamotron 3000. The device is a renovated karaoke boombox that snaps a picture when it hears you scream.

Billy Hunt, a commercial photographer and the inventor of the unusual device says it’s a therapeutic way to tap into the amygdala, the part of the brain that processes emotions and memories.

“Some people scream inward and some people scream outward … and some people go to crazy town,” Hunt told NPR. “I find it interesting how human emotion plays out.”

Screaming is considered therapeutic in some scientific circles. For example, Psychology Today reported on Dr. Arthur Janov’s primal therapy that claimed screaming and sobbing can release suppressed hurt from childhood and eliminate mental illness.

Also, humorous inventions have been dedicated to therapeutic screaming, such as ScreamBody, a backpack looking device that “silences the user’s screams so they may feel free to vocalize without fear of environmental retaliation,” at work or in public areas.
