This Thai lady has done a stunning piece of vector artwork with Adobe Illustrator, see it here.
I am struck with awe. Insane gradient meshes...I think she mentions 42 layers for the body alone. I've only just gotten used to gradient meshes - the sheer ambition involved in starting such a project is way beyond me.
See the rest of her work here. There's a good rendition of Frodo Baggins as well =)
