most (not all, some contributions are QTVR-only due to historical reasons)
many, but depends on photographer's choice of file upload (newer event = more likely to work) and your device's capabilities. You may experience slow playback, distorted images or unexpected browser quitting if there is only limited memory/GPU power available.
In this case I haven't selected my best panorama of the year 2007 but the best work I've done on 2007.
What we are seeing is the Museum of the religious celebration of the Semana Santa in Cuenca designed by Tiquitoc Producciones.
This museum is very special because it not only shows old pieces related to this celebration, but also helps the spectator to experience the sensations that someone can feel inside the procession. To achieve that emotional state, we used theatrical lights, evolving sound and a audiovisual spectacle guiding the public through the six rooms being the rest in complete darkness.
Our production company, mar de imágenes, designed and produced the audiovisuals of the whole museum including a documentary of 20 minutes.
