I've created a refrigerator magnet poetry site that uses your livejournal friends and interests as magnets. It uses DHTML for moving the magnets around, and when you save it, it generates a static image that you can link to from your journal. As your friends and enemies make art/vandalize your fridge, updates appear on the linked image. For now, you can even "cheat" and create your own words.

(Update: The directory where the source code was kept had improper permissions on it. If you tried to get the source code and failed, try again here.)
(Update 9/3: Apparently Mac users cannot drag-and-drop like PC users can. I don't have a Mac, so I would appreciate those of you who care to try out this alternate version of the toy: http://poetry.poisonkitty.net/index_wz.php?fridge=poisonkitty.
