Taiwanese artist Chen Chun-Hao doesn't use a brush or a pen, but a nail gun. He drives hundreds of thousands of nails into boards to recreate masterpieces by Chinese masters. By varying the size, depth and placement of the nails, he makes finely-detailed pointillistic images. View more photos of his work at the link.
