This would fall under, I wish I thought of that, category in my book. A father every year, probably much to the chagrin of his eager children, filmed them coming down the stairs on Christmas morning. You can see as the years go by the physical changes in the kids. What an amazing keepsake for  this particular family. It's not to late to start a tradition like this at your house. Imagine being able to share a quarter of a century of your family's most memorable moments for future generations.
