Do You Need an Idea for a Festive Christmas Door?

My colleague next door felt that I had given him a little competition with my Grapes of Math door earlier this year :), so he has festively decorated his door for each season this year.  This colleague exudes artistic talent and can construct just about anything with some colored bulletin board paper and cardboard.  This is his “gift” to everyone in the hall.  I just love it–and all out of bulletin board paper too!
