A group of students at the University of Dundee have created this interesting prototype called Sound Sculpted. The goal was to sculpt clay using sound files drive the sculpting arms. Ideally, you would end up with pieces of art that were unique to each piece of music. As you can see in the video (after the break), they did a pretty good job of building this thing and getting the arms to respond to the music. It is almost hypnotizing to watch.
We can’t help but notice that there is a bit of a design issue. Since the 4 arms are fixed vertically, and the clay spins on the same axis they are able to move on, your variation will be very limited. We think this doesn’t detract from the project, but does offer a large area for improvement.
How would you change the sculpting arms or their motion to make each piece more unique?
