Jonah recently reviewed an incredible performance art piece in Belgium.
Life: A User's Manual is a public performance by media artist Michelle Teran where she dresses up like a bag lady and carries an antenna made out of a soup can while pushing a shopping cart full of televisions along a designated route in Brussels, Belgium. The antenna is connected to a 2.4 GHZ X-10 video scanner which picks up signals from wireless cameras deployed by stores, homes, or police in the buildings and neighborhoods she passes. The found signal is the displayed on the TV in her cart. This type of surveillance is a theme of Teran's work that attempts to make hidden or private CCTV streams into public performance and online mappings. Really interesting take on the act of subverting existing surveillance tactics by displacing the context of the medium.
From her description:
"The city is a game board, where every story, every piece stands on its own, but is part of an intricate jigsaw puzzle. Both public physical spaces and private interior spaces contain traces of fragmentary personal [hi]stories tied together by an invisible network of media. How people inhabit the hidden 'image spaces', discovered by a wireless surveillance camera scanner, while at the same time inhabiting physical outdoor spaces, is revealed through the practice of walking."
