Archifon is a big interactive virtual musical instrument originally made for the Olomouc Baroque de-baptized chapel. Architectonical objects are re-interpreted by virtual visual elements via projection and sound. It is possible by mapping the virtual surface on the chapel's interior.

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.
