Starting 1996, Swiss artist Peter Regli has invented his own kind of art of anonymous intervention in public spaces. Like a hacker in the network, Regli breaks into selected existing spaces to challenge the perception. Reality Hacking, the book, has been awaited for quite a time and will be published in connection with Regli's first major solo show at Helmhaus, Zurich (until November 11, 2007). It features all interventions during the last eleven years around the world, and until now only published on the web. www.realityhacking.com
