Just stumbled across this Scream Body project. It's carried out by Kelly Dobson during 1998-2004.

ScreamBody is a portable space for screaming. When a user needs to scream but is in anynumber 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.

Why do I blog this? being myself a screamer to release a bit of pressure. I find it curious.
