Himalayas’ Head questions the way people interact with the environment. Players are invited to play snow war with opponents projected on the screens. Wearing lightweight head beacons with infrared LEDs, they control their movement in the virtual space. Soon they experience that things don’t seem to happen in a normal pace because the natural balance between their action and feedback is lost. Their movements are captured by a web cam and are calculated by a computer system which directs a 3D world and its dynamic 3D objects. Each participant controls one snowball, which reacts to her/his head movement, giving the sensation of floating through the landscape. In a hypnotic gaming situation, a game is given form by the players’ movements and social behaviour.
