The transparency 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.

It intercepts local network traffic and captures audio data, then the data is streamed anonymously to a dedicated server where it is mined for bits of emails, HTML code, images and audio material.

These are then neatly presented in the form of a feed that can be accessed when clicking on the red dot highlighting the place of the leakage on a map available online.

The ease of use and the mobility of this solution could make the transparency grenade a very powerful weapon in the hands of a concerned citizen or disgruntled civil servant.
