Since 'tis the season, I might as well plug my own holiday-themed game.
It's something I cooked up ages ago, using photos from my student dorm and what little I knew of Flash scripting. It's a kind of point-and-click game. Some have found it addictive, and it is definitely frustratingly illogical. But if you find the fox on a rock, he will give you hints!
EDIT: New and improved version is up!
