According to the new media artist and theorist Maurice Benayoun, the first piece of interactive art should be the work done by Parrhasius during his art contest with Zeuxis described by Pliny, in the fifth century B.C. when Zeuxis tried to unveil the painted curtain. The work takes its meaning from Zeuxis gesture and wouldn’t exist without it. Zeuxis, by its gesture, became part of Parrhasius’ work. This shows that the specificity of interactive art resides often less in the use of computers than in the quality of proposed “situations” and the “Other’s” involvement in the process of sensemaking. Nevertheless computers and real time computing made the task easier and opened the field of virtuality- the potential emergence of unexpected (although possibly pre-written) futures- to contemporary arts.
