de/Rastra by artist Kyle Evans – tube televisions repurposed as video art instruments:
The de/Rastra oscillographic synthesizer is a real-time audio/video instrument and computer-interfacing device that allows a performer to generate visualizations intrinsic to cathode ray tube technology while simultaneously creating the acoustic analog of the displayed imagery. The de/Rastra oscillographic synthesizer is an open source project and will eventually be accompanied by tutorials on methods of CRT hacking. Related tutorials can be found at http://www.crackedraytube.com/textstu… but specific information regarding de/Rastra are in progress.
