A lot of families put up Christmas trees for the holiday season. I was thinking that maybe each user could have their own personal tree and be able to decorate it with ornaments and little baubles that currently have little or no use.
Say, User X gets a tree (and maybe we could have a couple different trees to choose from). User X currently has a tone of little things stuck in his/her inventory, filling up space (these things can be candles, candies etc). User X can click on the item and there could be a 'Decorate Tree' option.
It would be like a virtual Christmas tree and you could add presents under them too if you'd like. Presents can be from other users.
I saw a Wrapping Service suggestoin form (can't remember who suggested this) which could correspond to the Christmas Trees. You could buy a gift for a user, wrap it up, then send it to their tree. They wouldn't be able to open it until Christmas Day.
