They arrived! Take a look at the shapeways page.
These are surfaces of constant width and are really quite fun. While they aren't spherical they roll perfectly, if you put all three on a table then put a book on top of them it rolls as if it were on ball bearings... The fun thing is the ball bearings aren't spherical, but it feels though they are!
These are three different constant width surfaces, one based on the Reuleaux triangle (bottom), one on the Reuleaux pentagon (top left) and one on the Reuleaux heptagon (top right).
