3D Printers Enter the Music Scene

So we've heard of 3D printing.  But, have we heard of 3D printers being used to play music? Rickard Dahlstrand explores alternate uses for the 3D printer, and as a result of generating a tune with the printer, found a new form of printed music.  So not only does the printer play music, it prints music (just not in the "notes on a staff" way we are used to seeing). I find this...incredible.  Take a look at this video and read more if you are so inclined.
