Since the rise of information theory we know that the processing of a signal always results in loss, there is always an element of friction. In the [RRTRN] three terminals are connected together via a single tape loop. Each terminal consists of a modified reel-to-reel tape deck and a computational work-station running a simple messaging program. Every message that a user on the terminal writes, will be modulated into sound, recorded on the tape and sent(=rolled) to the other terminals. There the received audio signal will be demodulated back into the message and it appears on the screen. By its particular setup the installation is classed in an unusual ring network topology, where information flows counter-clockwise.[RRTRN] deals with the materialisation of networks and reveals hidden technological layers and deals with contingency in the development of technology by considering media of the past and imagining different uses.
