Chances are good that someone has already done this, but I haven't found it (which means that I can sort-of claim it as my idea).

I propose the construction of a scrapbook - My Vacation in Berlin, for instance. Each page would contains photographs and a report on what's in them - the buildings I visited, the views from different well-known vantage points, items from a museum, interesting street scenes, and just about anything else that we take photographs of. But though the text would be mine, and faithful to my trip, the photographs accompanying the text would all be those of other tourists who visited those same places and posted their photographs of those same scenes on various sites.

Such a project would have to be a physical object, a scrapbook that people could hold in their hands. If it were executed digitally there'd be no reason to see it as any different from simply clicking into a photo site and viewing what's there. When perceived as a tangible object, however, the interaction between my experiences and their representation via what others photographed would raise what seem to me to be interesting and worthwhile questions. The definition of what's mine - the experience or the image of the experience - comes into focus.

Though I'm presenting this here as my idea, I don't object to someone else picking it up and running with it. If someone does, however, please let me know.
