This is a sound installation utilising Wave Field Synthesis, created for the Linux Audio Conference 2004, in Karlsruhe, Germany.
Scratch is a sonic creature, that makes scratchy sounds and moves around in space. The creature evolves itself and reacts to some extent on the audience.
This installation was the first attempt to create a model for an evolving creature. There are still a couple of things, which I want to improve on the algorithm, so there will surely be a “Scratch 2″ in one form or another.
