"passing by" is a multimedia installation created by Martina Menegon and Alexander Martinz. A cloud of virtual faces is projected on the floor. These masks constantly move around the projected area, following an invisible attractor while colliding with each other in an attempt to escape the constraint of the virtual space. Alexander Martinz's 4 channel composition follows the behaviour of these faces. Parts of the audio move with them, sounds get triggered by collisions and accelerated movements influence the pitch. "passing by" is an immersive experience in which the audio and the visual elements generate a mixed reality space that talks about the negotiation of the self, about identity, the body and media openness.
