Tron Legacy is Disney's 2010 sequel to the 1982 film Tron, with Jeff Bridges returning as Kevin Flynn, a programmer trapped inside a digital world called the Grid. In the film Flynn uses the phrase bio digital jazz to describe the miraculous isomorphic life forms that appeared there. The short, deadpan delivery later spread on soundboards and in edited clips, detached from the scene. It remains popular because the line sounds sincere and vague at once, making it easy to reuse for technology, glitches and odd digital discoveries.
