I've recently become slightly obsessed with Ron Mueck's just amazing lifelike sculpture. To make me an even bigger fan of his I found out on the wikipedia page about him that he used to work with Jim Henson and was one of the performers of Ludo in Labyrinth! I love that movie so much, I can practically recite every line.
If you aren't familiar with his work here are a few links:

(150mb so slow connections be warned, however it's totally worth it)
One thing that has irritated me reading article about him is the big deal made about his lack of formal art training. As if working in the special effects field didn't give him loads of training? Since I also have virtually no art training it really annoys me the emphasis that is put on attending art school by many people. Now I'm sure art school is a great experience and students learn a lot (and if I could I'd love to take a few classes). However I feel like art is a field where there are so many possible paths you can take to become an artist that one of those paths shouldn't be given all the emphasis as the "right" way to do it.
