In the artist’s own words:
My sculptures are all constructed with recycled materials — old CDs, computer hard drives etc, so I classify my work as “sustainable art”. They’re a lot of fun to make, but they take an extremely long time to finish, so I don’t do a lot of them.
He has a page on Deviant Art at: http://seanavery.deviantart.com/, and the work looks incredible. I wish more artists will make sure of these materials – materials that will last generations.
