"If you thought WikiLeaks was a disruptive idea, the transparency grenade is going to blow you away. This tiny bit of hardware hidden under the shell shaped like a classic Soviet F1 hand grenade allows you to leak information from anywhere just by pulling a pin. The device is essentially a small computer with a powerful wireless antenna and a microphone. Following 'detonation,' the grenade intercepts local network traffic and captures audio data, then makes the information immediately available online."
