 On the gallery walls Tiravanija featured the text of the US Constitution’s First Amendment (advocating freedom of speech), a history of radio and television communication in America, and simple directions for constructing low-tech broadcasting equipment.Tiravanija’s support of free speech is conveyed by his choice to broadcast the low-budget film "Punishment Park" (1971), a documentary on the suppression of Vietnam War protests.For the season 2006/2007 in the Vienna State Opera Rirkrit Tiravanija designed the large scale picture (176 sqm) "Fear Eats the Soul" as part of the exhibition series "Safety Curtain", conceived by museum in progress.
