The Transparency Grenade by Julian Oliver is a “weapon” for radical transparency. A case modeld after a Soviet F1 hand grenade contains a gumstick linux computer with wifi and an integrated microphone. The gumstick packet sniffs the wireless network while simultaneously streaming the ambient audio to a remote server for analysis. (Essentially, the gumstick is running DriftNet or EtherPEG.) In an interview with We-Make-Money-Not-Art, Oliver says that he wanted to make the “information war” a bit more visual and iconic.
