If you don't know Shaun Tan's work, you've been missing out. He writes and illustrates books that are ostensibly for children, but really go far beyond that. The Arrival, for example, is a picture book about a man arriving in a foreign city, a an alien world of weird Cthulu-esque creatures that he doesn't fit in to. The story is haunting and moving, told entirely through pictures, and the artwork is stunning.
I've only just gotten around to watching 'The Lost Thing', the film he made of his book of the same name that took home an Oscar for Best Short Animated Film. It's funny, and beautiful, and it will make you think about the way you live your life. Watch it here, then go and buy his books.
