I came across this article from Kronikle featuring the sculptures of artist Dalton Ghetti. I use pencils a lot, for drawing of course, but artist Dalton Ghetti would usually use these to make sculptures. His pencil sculptures are really mind-blowing works of art, carefully crafted, which took him years to master. I especially love the sculptures with hanging pieces.
