In the future, will you print musical instruments off your computer, instead of buying them at the local music store?
It may sound a bit 'flying car', but check out this demonstration video of the Zoybar TOR - an open source 3D printed guitar.
Zoybar is an open R&D Lab for academic, hobbyist, and commercial developers to create music instruments and applications.
In essence, instruments like the Tor can be modeled using open source 3d software. The models can be shared via the Internet.
Once you've designed your super-instrument, you can print it off using onine 3D printing services, like Shapeways. Material cost on the Tor was about US $175.
