In movies, whenever there is a scene of entering a large cathedral, an echo of choirs and organs usually becomes the soundtrack. In real life, that may not happen as often (if at all). However, the Olomouc chapel in Czech Republic, this can become a reality. In fact, you can make the angels sing.

Using projection mapping, visitors of this chapel can use laser pointers to interact with the architecture and beautiful statues within the chapel to create music. By directing the laser pointers, certain areas light up accompanied with a sound. Point your laser pointer to an angel statue, and will sing a certain note. Point your laser pointer to a window, and it will play chimes. This project allows visitors to become audiovisual composers, and makes the visit so much more fun and enjoyable (not to mention, allows the visitors to truly appreciate and become more observant all of the architecture within the chapel). Check out the video on how it works!
