PERFEKT DEVICE is a remix of urban art, action painting and social networks into a participative live performance in public space. The canvas is a temporary cover at Palais Rasumofsky in beautiful Vienna, Austria, and we'd love you to paint it with us by telling us what to do with our spraycans, pens and brushes.

Be here, write a line and pick a colour.

You'll find a chat and a cam here that will be live while we are on site in Vienna.That's 12.00-21.00 in London, or 5.00-14.00 in Managua. We'll also set up terminals in London, Paris and Barcelona if you want to meet us there. Follow us on Twitter or Facebook for more details.

World peace, godspeed and tiger blood.

Yours truly, PERFEKT WORLD
