![3D Projection Turns Baroque Church Into a Virtual Musical Instrument [VIDEO]](https://helios-i.mashable.com/imagery/archives/07g9v87G0JrXhHIybLR3TlG/hero-image.fill.size_1248x702.v1647020810.jpg)
An interesting 3D projection and music installation by projection mapping collective Macula transformed a Baroque church in the Czech Republic into a virtual musical instrument that could be interacted with using laser pointers. The virtual surface of the Olomouc Baroque de-baptized chapel’s interior was mapped, and parts of the architecture reinterpreted by virtual visual elements via projection and sound.
Up to 10 visitors could interact with the Archifon installation at a time, by directing laser pointers at more than 100 elements to trigger different audiovisual actions. Angel statues sing when the laser points at them, window parts represent tones of the different instruments, elements of the paintings play different soundscapes, and sliding up and down the pillars creates a range of visual effects. Take a look at the video below to see Archifon in action:
