Wow...umm, that's nice...I guess. ;) I agree maybe try to sway the vote towards drawing names for Christmas, maybe there are others ( I know it's small) that feel like you but haven't spoken up yet. Otherwise, I wouldn't stress too much. I'm willing to bet that any normal person would appreciate whatever you got them, even if it was only a $5 gas card or something!
I was also going to suggest baking something for that person in lieu of a gift. You can do a nice loaf of bread (I have a great banana, pumpkin and egg nog loaf recipe!) that you can always put in a nice bread dish that you can just give them as part of their gift...or bake it and wrap it up on a plastic plate...I honestly think either is just fine!
As far as actual gifts, if you don't know them well I'd probably go with something like a gift card or a dish of candies for their desk, or a even a coffee mug or something if they drink a lot of coffee. Candles or scent jars are nice or if their birthday is around a holiday so something holidayish and decorative.
Good luck, I hope it works out!
