Watch | Miniature pencil sculptures by artist in Taiwan

At his home in Taiwan's Yunlin County, miniature artist Lee Chien-chu peers through a magnifying glass to take a closer look at one of his latest works of art - the alphabet carved from the lead of a mechanical pencil. Lee creates miniature sculptures out of various types of pencil lead, all smaller than 0.5 centimetres in diameter. The material he uses - graphite, mechanical and coloured pencils - is cheap and easy to buy. Born in 1973, Lee took to pencil lead art just six years ago, and gets his ideas from a variety of subject matter, including Chinese culture, famous landmarks, and religion.
