I too have had the same question. This thread has been helpful for me.

One thing I did for my wife as a Christmas present was to make a Photostory slideshow using my pics (added music, captions, etc.) of the year's events. We had an eventful year- son's h.s. grad., his frosh year at university, etc. As we sit around on Christmas morning and watched using a borrowed LCD projector, we laughed, cried and relived a year's worth of memories.
