Looking for cool/fun math-themed gift

[dipole]

My girlfriend loves statistics, so I was thinking about getting her some kind of stat-related gift. I really don't have anything specific in mind yet though. A preliminary internet search hasn't pulled up much so far. Mostly just coffee mugs and t-shirts, neither of which are close to what I'm looking for.

I'm thinking something that she could place on her desk or in her bedroom. Something cute/fun/clever. If anyone knows of good websites/ebay stores/whatever that specialize in that sort of thing, please share!
