There's a short DVD of the event (I'm briefly in the middle of it - almost exactly, actually, just past the five minute mark on a ten minute video) in a card folder with some postcards, and a newsletter that - among other things - lists the benevols, the yellow-shirted volunteers (but it's the version of the list from the newsletter that came out during the event, and so is missing at least one person). Oh, and there's going to be a book, with pictures, and people's memories and stuff.
And that reminds me, of course, that I've not posted my full write-up yet....
