||Combining aspects of engineering with traditions of studio art we investigate an interface between both worlds: using a substantial acumulation of electrodigital refuse, taken as a .raw expressive medium., an elective course ( TAP: .taller de arte y programacion. . Studio of art and programing. ) takes a large mixed group of students ( engineering, art, architecture, music, etc..) with very different levels of skills, for a sustained immersion into an exploration context. Eliminating in a large measure the problem of .costs. by using obsolete, discarded computer parts, students manipulate, observe, deconstruct, reconstruct functional hardware and use programming to produce an expressive documentation of the process. The objective is not to work on .products. but on the production of .symbolic value. by uncovering and staging the fundamentals of electro-digital-computational knowledge into a form of .theater of technology..
