Another minimalist networked installation is Less Than Three (images above and below) by Rafael Lozano-Hemmer. The installation exists in two versions. The first, pictured above, uses white light emitting diode strips while the second smaller version, pictured below, uses red electro-luminiscent wires. The installation is:

a network between two intercoms. As a participant speaks into an intercom, his or her voice is translated into corresponding flashes of light and this light pattern is transmitted visually along one of the several possible pathways through the network. When it reaches the other side, the viewer’s phrase is once again released as sound. Several voices can be carried simultaneously and the short contributions travel fast through the network and the longer ones taje [sic] longer.
