p-tex will be exploring how computer musicians can perform and create music without the need for mains electric, and using low budget or recycled / salvaged equipment and free open source software. He will also be using various sensors that will be manipulated and triggered by the surrounding environment, as well as by visitors to the site. p-tex has created software patches specifically for the piece which enable the sensors to communicate with the computer equipment. To achieve this he has used free software puredata and processing. For directions to Heysham Barrows, go here.
