An advanced, Flash based presentation of the City of Opole which contains 25 spherical panoramas. Th emain menu was embedded in 3D space of panorama of the old town. A series of realism increasing mechanisms were used, i.a. special effects (for example an airliner at the night sky), sound hotspots – sound generators, precisely placed in 3D space which change volume depending on the direction of view (for example the sound of organ in chapel clearly comes from the door to nave).
