pppd is a highly formalized audiovisual composition built around the esoteric programming language p'' ("p prime prime"). During each brief scene, a random sequence of p'' code is generated and run, while the memory it uses is visualized and sonified. pppd is an artistic re-imagining of the otherwise academic field of computability theory. It functions simultaneously as an investigation of complex behavior emerging from formally simple systems, and as a playful exploration of computational dreams.
p'' is a subset of the programming language better known as Brainfuck.
