Pompeii's Ruins to Be Reconstructed by Robot

Imagine you have a jigsaw puzzle with 10,000 pieces but no picture on a box. In fact, you don't even have the box--it was destroyed nearly 2,000 years ago. These puzzle pieces are fragments of frescoes in the ancient Roman city of Pompeii that were leveled or buried by the eruption of Mount Vesuvius in A.D. 79. Some pieces are missing, others are broken. And instead of being precisely-cut shapes designed to neatly interlock, they're damaged, irregular fragments.
