My DS2 completed his first knitting project -- a bunny mask -- a couple of weeks ago. I'm really proud of how well he did.
He's going to wear the mask during a charity online video-game-playing marathon just after the first of next year. As I understand it, for the game he's going to be playing, the main character pretends to be a rabbit for a while. He's going to don the mask for that section of the game.

The hat is a combination of two different patterns: a panda ski mask pattern for the main part of the hat -- with changes to the nose and mouth to make it more bunny like -- and a bunny ears pattern for the ears. (I scouted the patterns for him.)
I didn't tell him how difficult the pattern was until he was finished. ;)
