Bernard Fisher distinguished four models of artwork representations . One of them is Postmodern Model, which characteristic feature is interactivity. This model, based in 20th and 21st centuries, have the widest range of tools, such as: logic, mathematics, visualization, thought experiments and computer science.
Interactivity as a feature of works of art, influence the recipient in special way. He has opportunity to take the action that can put a significant mark on shape of the final work. It is kind of dialogue between the artist (creator) and the recipient or even invitation to the process of the creation.
If we assume that dance or any type of movement can be an art, good example to describe essence of Postmodern Model is the “Glowflow” (1969), the first project of Myron Krueger. It was consisted of a darkened room in which the walls were made of four transparent tubes, changing the colour inside by pumping into them fluorescent particles. All of this was taking place with the accompaniment of the Moog synthesizer sounds. Movements of the viewer, who was located inside the darkroom, were interpreted by a computer that was simultaneously responding on them with light and sound signals.
That computer controlled environment, created specific representation of human body movements, what can became the great show of colours, light and sound. Thus that average viewer can became an artist. The only thing he has to do is to participate: get inside and move a little bit.
In a conclusion I want to emphasize that the interactivity is one of the most important features of the Modern Culture. This kind of interaction help the art works recipients achieve the higher level of sensation.
