The 4th Wall app is a free, augmented reality public art platform exploring resistance and inclusive creative expression. The app invites viewers to scale, rotate, move through, place and record Nancy Baker Cahill's AR drawings in 360 degrees. It also offers access to the artist's LA studio, and a hologram of her talking about the conceptual underpinnings of her work. Viewers can record the AR artworks anywhere in the world, creating their own context for the works. 4th Wall also includes the site-specific, collaborative public art feature, “Coordinates”.
4th Wall will be activated in different spaces around the festival and the city of Barcelona.

In the ImmersiveHub you can also experience the virtual reality pieces "Revolutions", located at the crossroads of Tipton Road and Route 111. This experience imagines the Palm Springs desert as an AI garden that reflects on the fate of the desert and clean energies. And "Margin of Error", located in Salton Sea, an area marked by toxic environmental damage that makes the user consider the ungovernability of nature.
