Advent Gimmick

I was looking back over my 2006 blog Advent calendar which was pretty darned cool. I thought it might be nice to celebrate the season by another such gimmick but not sure what that should be. So I will do something but I'm not quite sure what it'll be.
In the meantime,I'm not sure it'll be this:
One Hundred Days to Make me a Better Person
Maybe you'll be making the pledge?
