"Margaret Sanger: A Public Nuisance," co-directed with Svoboda, was selected by The Getty as one of two examples of outstanding experimental biography of the 90's. Bull's videos won the grand prize at the Bucks County Film Festival, the experimental prize at the Atlanta Film Festival, and were screened at MoMA, Atlanta Film Festival, Athens Film Festival, Cleveland Film Festival, Cork Film Festival, Humboldt Film Festival, Creative Time, The Kitchen, Brazil 10 city tour, and a New York State tour. Grants from NYSCA and Experimental TV Center allowed him to develop Cellphonia, a karaoke cell phone installation that showed at ZeroOne San Jose, NIME 2007 and 2009, EAT Revisited, and ICMC 2010 in Brooklyn. Bull was in residence at Bellagio in 2005, producing video for Svoboda's RedCat opera WET.
