The music sequencing generated by sequences of objects materializes one made by some luster with the software programs, transferring the habits of juxtaposition of the sound samples in a physically accessible, and fulfilling from a point of view muscle. To gratify the gesture is Instant City by Sybille Hauert and Daniel Reichmuth, an installation that allows you to outline melodies through an architecture to build with bricks transparent placed on a table. The playful aspect is predominant in the implicit invitation to experience the effects of positional changes as well as in sharing more active users around the square table. Technically, the position of the various elements is given by the light they diminish with their transparency, detected by sensors placed under the floor of the 'game'. The work closely resembles the concept of Audiopad , in which the objects as well positioned on a plane not regular, were detected via microtransmitters incorporated. The levels of reading, this time, however, may be different, dall'eterea transparency of the elements which makes them equal to each other and neutral, leaving the spatial location their characterization. As well as the structure of the gaming table lit from above for reasons detection techniques, for its monolithic appearance and driving in a dark space attracts patrons eager to overlook this sound space delimited and, ultimately, identified from space light that is able to occupy and making audible.
