I've visited the following site every year for the past 3 years or so. Each year, Leslie Harpold puts together a lovely online Advent calendar. Each day in December is clickable (of course you can't click on a date before it actually arrives - no cheating!), and it includes a daily surprise, a fun link, and a Christmas memory. Leslie has posted her own memories in the past years, but started posting "Guest Memories" last year (I believe). Each day is a fun little 5 minute diversion from the normal grind.
Hope it helps to get you into the holiday spirit and that you have a little fun with it in the days leading up to Christmas.
