!f Istanbul International Film Festival always keeps up with the avant-garde forms of art. Each year the opening gala of the festival also hosts a world premier of a movie. And before the movie, they arrange a show to surprise their audience. In a cinema hall with IMAX stereoscopic 3D projector setup in one of the most crowded shopping malls in Istanbul, and live music setup, in harmony with that year’s theme “People Power”, a real-time sound-reactive stereoscopic audio-visual show has emerged. The system was setup in such a way that at the end of the show, the audience was able to play with the visuals via clapping, emphasizing the “People Power” theme.
