I'm a sculptor and i'm normally right handed except when i sculpt. The left hand works much better at that, requires a lot less decision making as it seems to work directly whereas the right hand works through my conscious. Of course thats not what this article is about, but since nobody else has written anything here i thought i'd just pipe up. I'll be checking my sculptures for facial sides now thanks to the article. They often have two slightly diff expressions on em, have to admit.
