How about stories from kids, grandkids, nieces, nephews, friends, etc. Kind of like, "My foundest memory of Uncle ...." Then compile these into a scrapbook or sorts.

You'd be surprised that people remember the little things and if he'd really like a few dinner homes then this is something he can read over and over while he's alone.

Here's an example, if I were writing about one of my mother's sisters, I would recall the time I was 9 years old and I went over to help my aunt write her Christmas cards. (My aunt had very poor eyesite, and was legally blind.) I addressed the envelopes and wrote a note on each card that my aunt dictated for me. I also put on the stamp and a return address label. Being 9 I guess I was not very picky about how straight I put on the stamp and label. My aunt looked over the cards and told me everyone was going to think she was drunk because the stamp and label were a bit crooked. I was worried because I believed her and thought the people might actually think that.

It's just a cute little story, only my aunt and I would remember and appreciate but if she were still alive, it is the kind of thing she'd enjoy reminiscing about.
