Joybubbles is a feature-length documentary film directed by Rachael Morrison, about a blind telephone hacker who legally changed his name from Joe Engressia Jr. to Joybubbles, after declaring himself the age of five forever. Joybubbles was one of the first Phone Phreaks, a group of pre-internet phone hackers, and remains the most legendary figure of the phone phreaking community. Joybubbles was recently featured on WNYC's Radiolab podcast.
