American artist Jen Maestre does it with pencils ... er ... sculpture, that is. This pseudo sea urchin with seductive orifices is entirely made up of pencils. The pink bits are the rubbers on the tops of the pencils. She cuts her pencils into 1-inch sections and sews them all together using a peyote stitch. The Telegraph has put a gallery of her works online (title link). I must admit by the end of it the idea seems to have lost its point. You've seen one sea urchin sculpted out of pencils, you've seen them all.
