If you liked the ‘Extending the Touchscreen’ project by Michael Knuepfel here are a few experiments by Benjamin Gaulon using displays to convert light to sound waves. He writes:

Research and recent innovations have led to an amazing increase of types and uses of visual displays and screens; indeed, in our predominantly visual culture, they are everywhere. A typical person carries at least one device with a screen, is presented with them in public places, uses them at work and in many leisure activities. They are so ingrained in our everyday acts and habits that we don’t even notice them anymore. L.S.D invites its users to engage in a new perception of their daily environment. In ecology this class of relationship is called commensalism.

L.S.D feeds on light via two LDR (light depending resistor) mounted on a suction cup, allowing the sensors to be mounted on any screen surface. An analogue synthesizer converts the light input to sound waves. This device can be used in many different configurations and feeds from any light sources. Even if L.S.D can be controlled by any light source, its design is aimed at screen reading/listening. More videos on Ben’s vimeo.

Benjamin Gaulon is a researcher, artist with a broad experience of acting as art consultant, public and conference speaker, graphic designer and art college lecturer. Issues like e-waste, obsolescence and disposable society have been the focus of his practice and theoretical research. ‘Recyclism’ research seek to establish an inter-disciplinary practice and collaborations by creating bridges between art, science and activism, and by doing so, shifting the boundaries between art, engineering and sustainable strategies.

Back in 2010, trying to find a flat screen for his final project, Ishac Bertran found one on the trash that seemed ok. Unfortunately the VGA connector was broken but he managed to use the DV only to realise that the screen was also cracked. As it was useless (for normal purposes) he cracked it a bit more, pushing the liquid crystal move along the cracks with a screwdriver and produced these beautiful images below.

The Scan Processor Studies are a collection of works by Woody Vasulka & Brian O’Reilly.

The full work is of total approximate duration of 45 minutes, with sections of various lengths, textures, and dynamic qualities.

The works use sources excavated directly from the output of the Rutt-Etra Scan Processor of the 1970′s, as well as further manipulations using Tom Demeyer’s ImX software, developed with input from Steina. Extensive editing and layering and additional augmentations were done using Phil Mortons IP. The Sound was generated (mostly) by custom software developed by Chandrasekhar Ramakrishnan and myself called NETHER GENERATOR, which sets up a number of complex real time feedback networks filtered and processed by various means.
