Im filmischen Werk des russischen Regisseurs Andrej Tarkowskijs sind an markanten Stellen Spiegel zu sehen. Ein Film trägt sogar den Namen des Objektes. Vom einfachen Spiegel ausgehend wird der Prozess der Spiegelung über verschiedene Abstraktions- und Transformationsstufen ausgearbeitet. Der Spiegel wird als Objekt und Metapher ganz hinter sich gelassen und zur zentralen filmischen Konstruktionsmaschine, dem Kinematographen, entwickelt und theoretisch interpretiert. Hierzu wird von Andrej Tarkowskijs Filmen ausgegangen und von seinen Schriften her das theoretische Instrumentarium erarbeitet, das sich an entscheidenden Stellen mit filmtheoretischen Kategorien von Gilles Deleuze trifft. Der zweite Teil dokumentiert die theatralische Umsetzung des nicht realisierten Szenarios "Hoffmanniana" von Andrej Tarkowskij in dessen Zentrum ein Spiegel steht. Hierzu wird der literarische Text im Zusammenhang des tarkowskijschen Filmwerkes als "Kinotext" interpretiert, d.h. auf seine kinematographischen Konstruktionselemente hin gelesen, "gesehen" und "gehört". / Films from Russian director Andrei Tarkovski often present mirors in various situations. One of his films is even named "The mirror". The reflection process starts from a simple mirror up to many levels of abstraction and transformation. Beyond mirrors as mere objects, or simple metaphors, the tarkovskian concept of "construction-machine" of cinema (i.e. the cinematographe) is described. Additionnal theoretical elements of my work are based on Andrei Tarkovskies films and many writings; they will coincide with the film theory of French philosopher Gilles Deleuze. Another part of this work deals with the staged version of "Hoffmanniana" (script by Tarkovski, the film was was never shot) tha I directed: The poetic scenario is seen through Andrei Tarkovskies other films, considered as "film material2 and analysed in terms of visual and musical elements.

The subject of the thesis Live images of VJing is an aesthetic activity, based on visual projections and on work with new media in real-time, known as VJing, or more generally "live audiovisual performance". As these performances usually complement auditory events or are supplemented by music. The first part follows the origins of VJing out of three angles: First the historical development of projected image, electronic music and the discourse of synaesthesia principle as an principle joining different sensory perceptions into one. Second part of this thesis is introducing an philosophical perspective and it's defining terms, through which can be glimpsed the tendencies in the development of contemporary art of new media, particularly following the example of the German new-media philosophy with terms like homöotechnik, performativity, mediality and gesture. The outcome of this thesis is the finding, that it's not the media-philosophy bringing the textures and shapes to VJing, but the opposite - VJing as an art form is a valuable contribution to defining of the media-philosophy, which seem to be forming along with the new media itself and with the experimental arts exploring it's radical possibilities.
