A message board that I frequent does this a few times a year. We take pictures of our day, upload them, caption, and show each other what we do for an entire day. I've not taken part in one before, mostly because I forget, but I gave it a shot this time. Not terribly interesting, but here ya go, if you're interested:
I'd love to see one that you guys do! Send me a link if you end up trying it. It was kind of fun, actually.
