Robert Barry I would say its the energy
thats my art...

• I guess it was the first invisible art. It
  could not be perceived directly... in the
  January 1968 Show (Seth Siegelaub) I included
  several carrier wave pieces. One was called
  88mc Carrier Wave (FM) and another 1600 kc
  Carrier Wave AM...

Not shocked by news anymore?

• WiFi-SM by Christophe Bruno (October 2003)
• WiFi-SM is an Internet connected wireless device
  that you can put on any part of your body. It
  auto-matically scans online news sources and each
  time it finds one of your key words (Iran,
  Iraq or

Darfour for example) your WiFi-SM is activated,
giving you a mild electric shock. Guaranteed to
reduce guilt or your money back! http//www.unbeha

  the city, these invisible stories... Am I
  invading someones private space or are they
  coming into mine?

  you walk down the street, you're walking through
  an adventure world draped on top of the real
  world...
