The production of electronic artifacts is increasingly confronted with the technology as such, the state of the art hardware and software that often offer good opportunities for new interpretations. The more complex the comparison with the computer a few years ago, and for the different processing capabilities, both for the difference of interfaces, protocols and standards provided. On the other hand, however, the reuse of old machines for the production of visions posthumous installations can take advantage of technology, and then assemble them in a new light. ComputersForArt.org is a non-profit organization of Glasgow which is aimed at this, ie collect technologie surplus to make them available to artists who want to take advantage for their own work. The amount of material collected was probably influenced by the approach taken, we often use a considerable number of machines, focusing on the idea of ​​a work which makes the composition of different autonomous entities that can be used thanks to their affordability. Among those laid out can indicate Chant by Sandy Smith, for example, where forty Apple computers do make a speech software that reads text (text-to-speech) consists of long strings of vowels and collectively express a Gregorian chant choir , or Untitled (The Sky is Blue) by the same author, which has formed a cylinder machines accesse with their monitor within which the blue light of the latter invests the viewer together with the heavy magnetic field generated by the set of machines in operation.
