Once upon a time I became noctornal and created an owl overnight. I'd wanted to make an owl out of pencil sharpenings for a while, since seeing a photograph of a particularly smart-looking one in a wildlife magazine. Its overlapping feathers struck me as very similar to the wooden waste of our graphitey friends, so I knew it would make sense to recreate it this way. And here's the result, pre-framing and free as, well a bird.
What I like most about the resulting image is that the whole thing is made from a tree, including the paper.
...Unless you count the blue tac behind all those shavings, shhhhhh. Our secret.
