The Victoria & Albert Museum's website has a section on knitted things that aren't garments. You can submit your own picture. I love the jellyfish1 and 2; must make one for Thing 2, whose room has an undersea theme. And Knatolee, there is a knitted cow sling! But the best is the Flying Spaghetti Monster, complete with link to the pattern. I posted about the FSM some time ago; you can read about it here.
The V&A site has other interesting knitting stuff, too, including patterns. Check out the Conrad gloves.
