This is incredible. Together with master LEGO builder Rene Hoffmeister, Lorenz Lnggrtnr and his team helped construct a working barrel organ that used LEGO Star Wars characters on a rotating barrel to play music from Star Wars. The organ works by rotating and having the surface objects hit LEGO triggers that in turn play a note on an electronic organ.

Here’s a video of it in action.

Here’s how it was made.
