I interviewed Ron for a book once... he's the nicest, gentlest, most NORMAL guy in real life. He's just staggeringly good at what he does. He learned his trade (the foundations of it, at any rate) in Jim Henson's Creature Shop in London, building puppets for The Dark Crystal and Labyrinth. Hoggle, the giant in Labyrinth, was one of his, IIRC. As time went on, he was working on ever more realistic puppets (I think for a John Boorman movie of The Lion, the Witch and the Wardrobe), and as you can see, he became a master of skin and hair made from foam and latex and acrylic thread... When the Boorman film fell though, he went back to Australia to try his luck as a fine artist, and as you can see, it worked out OK for him!
_I_ still remember him, though, as the quietly passionate craftsman who gave an entire afternoon to the geeky writer in the coffee room...
