Introducing...the ScreamBody, a portable space for screaming!
When a user needs to scream but is in any number of situations where it is just not permitted, ScreamBody silences the user's screams so they may feel free to vocalize without fear of environmental retaliation, and at the same time records the scream for later release where, when, and how the user chooses.
I imagine this would be quite handy on the streets (or subways) of Seoul.
I could definitely use one of these. Though access to a car and highway also works wonders these days.
