The idea of trust in the telematic interaction is a recurrent theme in this exhibition, and it makes sense, as all of the pieces require some sort of interactive relationship. You have to give something to get something. Steve Mann's "Seatsale," for example, requires you to swipe a credit card or any other form of identification with a magnetic strip to experience the project. I felt extremely reluctant to dig into my wallet for a piece of plastic, an oddly hypocritical response based on the ease in which I'll trustingly insert my ATM card into all manner of potentially bank-account draining slots.

But after the gallery attendant bravely activated the piece with her Visa card, I followed suit. This enabled me to sit in an elaborately rigged chair and witness a paranoia-infused video documenting a trip to Sears in which the man behind the camera asks various salespeople about the surveillance cameras. Some of the clerks are more forthcoming than others about the fact that security cameras are there to catch shoplifters. After a while, a shrill alarm buzzer rings a warning that if you don't get up, something like those tire puncturing grates in parking lots will rise out of the seat and jab you in the heinie.

The latter elements just seemed silly and superfluous compared to the real cultural challenge posed by the uneasy knowledge that you swiped your card and it took your personal info -- to add your identity to a database perhaps? One doesn't know.
