This is a really cool project, good job!
Spoon is an interesting example : http://imgessence.com/browse/view/190 - You can see the many basic outlines of a 'spoony' shape. However, all of those images of spoon are presenting the object rotated at some more or less random angles. It would be interesting to add some algorithm that would try to match the images (rotate / scale) to the average and hence give less noisy output.
