Exist.pl by Páll Thayer
Exist.pl is an exploration of the metaphysical and ontological qualities of a computer program. It is designed as an introspective analysis conducted by the program itself, producing no output in the process. It begins with a Cartesian reduction. Through a traditional version-based evolution of software, a single program is provided with increasingly complex methods for examining and perhaps understanding its own existence and state of being.
Image Scan Sequencer by Gijs Gieskes
The image scan sequencer scans images and plays them back as midi notes. In the image scan sequencer installation, a scanner is connected to a midi decoder, made with arduino, that controls a bent chip. The image is being generated with a php script, and plays back midi notes that sound a lot like generative music.
