This photo of the back of a photo was posted yesterday on Paper Cuts, the New York Times book blog. I love the juxtaposition of so many kinds of text–handwritten notes in pen and pencil, stamps in different colored inks, pasted on bits of newsprint.
Digital objects can develop their own patina (like the digressions on digressions in the conversations on a good Wordie word), but some kinds of beauty require this sort of physical manipulation over time.
The Twombly link in the second comment on the original post is worth following, too.
