1993 – Various formats, Production: Egon March Institute & Andrej Kregar, VPK, Ljubljana, 11' Script & Dir: Marko Kosnik, Camera: Špela Virant, Marko Košnik, Silvo Zupančič, Smiljan Šiška, Edit: Andrej Kregar

Egon March Institute performances with electro-acoustic plates, presented in Hamburg, Ljubljana and Bauhaus Dessau, the video projections were made according to precise calculations for each space separately to create the correlation between the elements of picture and the dimensions, shadows and movements of the plates in the space. The video shows fragments from performances and it also demonstrates the operation of a sonorostat - a sonorous object-plate that stimulates special acoustic phenomena merely by changing position in space. The plates were carried and 'played' by the performers according to a precisely programmed choreography and thus changed into a dynamic scenic sculpture, which cut through the perception of space perspective and screen surface.
