Wireless video transmission broadcasted real-time image of the city square at two vis-a-vis locations at the square. Wide angle image was captured with camera positioned at the top of lamp at the meedle of square. Sites with projections was Gradska loza [reinessance city court, today art galllery] and Gradska straza [baroque city watch, today Etnographic museum].  The city watch not working for already ten years becouse of reconstruction, so it was possible to install back projection at the clock transparent background.
