Cerkahegyzo is a Hungarian artist whose delicate pencil sculptures have recently been making the rounds on the web. Time, patience, sandpaper, needles, and razor blades are all the tools he needs to make these seemingly impossible sculptures. He admits that his work was inspired by Dalton Ghetti, the original pencil carver. He has even paid him homage by with similar carvings of a heart, linked chains, and a screw.
