The aim of this diploma thesis is to make available and analyze the production called Revue from the Case, which premiered on the experimental stage of the State Theatrical Studio Prague on March 25, 1968. This premiere was preceded by the successes of individual parts of the production at EXPO 58 in Brussels and EXPO 67 in Montreal. Based on the preserved archive materials for this production, whose main authors were Ladislav Rychman, Jiří Procházka and Jaromír Staněk, I will also attempt to name the basic principles, benefits and limits of Laterna magika.

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.
