Art Films are a growing trend. As an art collector and a burner I'm happy about this trend. Sotheby's just launched an art interview with the film director who came to the 2018 Burning Man Festival and is releasing a film all about the art. While the burn is not commercial and needs to abstain from any commercial influences to retain it's alter-universe perfect world it has been nice to see the Art of Burning man outside of Black Rock City.
From art around Reno, Nevada and the Smithsonian in 2018 (I believe was the year) had previous art pieces that survived the burn so others that haven't made it out to the desert experience can get a small piece of what it's like out there. It's a way to help expand BRC for the normal people of the world and helps expand the world's interest in art.
