Barilla, the giant pasta and pastry manufacturer, commissioned a 3D pasta shape contest. The winners can be seen at this page. My initial reaction is that this is a gimmick, but one of them did strike my fancy. It's called lune (moons), shown below.
What I ask myself, of course, is how well these computer-generated shapes will hold up in actual cooking e.g. take to sauce, lend themselves to various cooking techniques etc. I also think that it might be a good idea if someone were to catalogue the enormous variety of pasta shapes that have been generated by humans over the centuries. And preserve the rapidly-disappearing oral tradition of Italian regional home cooking.
Barilla actually is looking into the possibility of equipping restaurants with 3D printers. Should be interesting.
