The installation represents and displays the different operations of the performance: 100 telephones are directly connected to the computer calling the people at home and thus connecting them with the opera performance. The machine constantly monitors to see if the bug is still emiting its signal. As soon as the bug detects the machine switches into LIVE mode and starts to automatically call the phone numbers listed in the Zurich telephone book. In the installation the telephones start ringing in time with the phone of the person called. As soon as someone at the other end of the line picks up the phone, the telephones in the exhibition, like the telephone at the persons house are connected to the opera. The monitors show the number being called, the opera played and other such output information.
