______ The video mapping created for the building of the Municipal Library in Mariánské náměstí is a monumental dynamic fresco depicting the processes and rhythms in the depths of the ocean. We invites the viewer to journey beyond the limits of ordinary experience and into the dark underwater currents that periodically carry away vital resources. The projection is a visual concert and a dancing riot of colours, while surprising with the sound design of an analogue synthesizer by American musician Suzanne Ciani. Viewers are thus treated to a riveting look at one of the most important factors in maintaining the balance of climatic parameters necessary to sustain life on the planet as a wild and untamed element. For the paradox of maintaining balance is constant movement.
