The collaborative audio AR app Radical Atmospheres was selected to be in the 50th issue of The New River Journal of electronic literature and digital media. This project is an audio walking tour of radical Puerto Rican activism in East Harlem. It was created in Prof. Andrew Demirjian’s Spaces Speak class in the IMA MFA program. The audio is a combination of sound poetry made with archival materials from CENTRO archives and oral histories conducted over a year.
