I saw this post on Design Sponge today and I couldn't not re-post it.
Dalton Ghetti's art is incredible! I can't believe that someone can create sculptures this small out of something so brittle as pencil lead. He spends anywhere from a few months to a few years creating one tiny sculpture-- with a razor blade and a sewing needle-- and no magnifying glass. A carpenter by trade and artist on the side, Ghetti spends an hour to an hour-and-a-half per day working on a pencil sculpture. Any longer than that, and his eyes get too tired. Take a look and you'll see why.
