Archifon is a project by musician and multimedia artist Tomáš Dvořák and visual artist Dan Gregor, originally made for the Olomouc Baroque de-baptized chapel in 2011. The second edition has been installed in the Royal Chapel of Protestante Church for the Nuit Blanche Festival in Brussels.
Archifon II is a large and interactive virtual musical instrument controlled with laser pointers. Architectural spaces have been projection-mapped and the surfaces project imagery and sounds whenever they are touched by the beam of a laser pointer.
The digital overlay is made up of musical elements like strings, flute, steel drums, voice of prayer, angels singing and slider effects, all set off when pointed at. Up to twenty visitors at a time can interact with Archifon II by using the laser pointers. You can check out the interactive installation in the video below:
