There's a museum in Florence that I went to where you could see many statues in various states of completion. It was fantastically beautiful. They were clearly not complete works, Michelangelo had intended to do more. But for whatever reason they never were finished. Despite their state of incompleteness, you could see the craftsmanship involved in getting them to their current state. But you could also see beauty in this unfinished state, as if the men (predominantly) of stone were climbing out of the rocks themselves.

Show someone an image of the Statue of David and it's not that interesting. But see it in person. The immenseness of it. The detail that went into it. See these other statues nearby, like stone timelapse photos. The whole thing is quite fascinating (intellectually) and can be quite emotionally moving (not in the sense that it brought me to tears, but more of an awestruck feeling seeing this work).
