a satellite link to connect in real time one location in Los Angeles with another in New York. Chance passers-by could use the «Hole in Space» to establish visual and acoustic contact with people at the other end of the USA.

Richard Kriesche's «telematic sculptures» are a good example of telematic projects. After examining the significance of background noise in technical or satellite communications in various performances such as «Radio Time» (1988) and «Artsat» (1991), Kriesche collaborated with Peter Gerwin Hoffmann to create «Telesculpture III» (1993). This sculpture consisted of a twenty-four-meter-long section of train track that was transported across the exhibition space by a twenty-meter-long conveyor belt. The track's slow but constant movement towards the wall was triggered by telephone calls received within the scope of a project by Fred Forest.[19] The number and information content of the calls determined whether or not the track would be pushed up against the wall and smash the monitor strapped to its end in the process–the telephone calls therefore initiated a movement directed against another medium. This linkage with the

telephone network gave rise to complex interaction. As the first worldwide information and communications network, the international telephone system supplied «Telesculpture III» with controlling impulses, and overruled the sculpture's spatial boundaries. For the Austrian Pavilion at the 1995 Venice Biennial, Kriesche expanded his concept to produce «Telematic Sculpture 4» (T.S.4), in which a train track is continuously moved by the data streams on the Internet. Each time somebody logged into «T.S.4,» the sculpture was temporarily brought to a standstill. The entire volume of data streams, and with them the concrete movement of the sculpture through the pavilion, was displayed on a monitor as status information.

By contrast, the works of Paul Sermon clearly aim at interpersonal, often almost intimate, communication, and are conceptually linked with the «Hole in Space» project of Galloway and Rabinowitz. «Telematic Dreaming» (1992) was Sermon's first project in a series of telematic installations linking two remote locations over blue-box technology and ISDN video conferencing.
