> it's easy to understand why it died out I think it's probably more sociological than technical. People love to see themselves and their friends/family. My work has screens that show photos of events and it always causes a bit of a stir ("Did you see X's photo from the summer picnic?") Yearbooks are perennially popular and there's a whole slew of social media. However, for this to be "fun", there must be a decent chance that most people in the audience know a few people in a few of the pictures. I can't imagine this working well in a big city, for example, or a rural theatre that draws from a huge area.
