If you haven't seen it before, take a moment to watch this clip from an American television show called Mad Men. It's a show about a group of people working at Madison Avenue (in New York City) advertising firms in the 1960's.

I felt pretty moved the first time I saw that clip. I still feel moved when I watch it. For a moment, I wanted a slide projector. All of the people I know who also watch the show felt it was a master stroke. Nostalgia is a powerful selling force.
i like it, it's cute, cheap enough to be a fun gift, and the kind of ridiculous steps your photos have to go through appeals. kind of like http://instacrt.com/
Cute, fun gift? I guess yeah, but again, why only instagram? Oh well. I realize of course that I'm not at all their target audience.
