hi, let me pls introduce our new interactive installation called Archifon.)
Archifon is a virtual musical instrument using building surface, which you can controll with laser pointers. Architectonical objects are re-interpreted by virtual visual elements via projection and sound. Up to ten visitors at a time can interact with the Archifon through the laser pointers. By pointing on any of more than 100 elements different audiovisual actions are initiated.
