Wave Writer is an extended version of Temporal Intervals. It took place in Tallinn, Estonia as part of ISEA2004. Here, I had the opportunity to reconfigure the original work for a new gallery space and to explore the ways that developing internet technologies at that time enabled viewers in other locations to log onto the Wave Writer website and interact with both the machines and the participants in the real-time gallery space. Consequently, once again, the structure of the installation created a complex interplay between participants, machines and locations – with a particular emphasis on international engagement through widespread publicity in connection with ISEA.
