I was reading in "Writing Machines" about Phillip's art book that was created from Mallock's novel. In one part she writes (I'm looking for the quote now but I can't seem to find it) that Phillips said that if the novel sold well he could do 12 new pages and substitute them in the book so that the nth edition might not include any pieces from the original.
I really enjoyed reading "Kind of Blue." I thought the story itself was compelling and it was nice to have the reading broken up into little pieces (e-mails). E-mail is an interesting platform for a novel because it is virtually all dialogue. We only know what the characters themselves know (either they have written the e-mails or they have received them). Granted, we have acess to the e-mail boxes of many characters, so we have slightly more information, but all of the information we're reading was read by at least two characters.
Shelley Jackson experiments with new ways to write. One of her recent projects is called "Skin" -- a story in tattoos on the bodies of 2095 volunteers. Her website has links to other experiments, such as a collaboration with her sister about dolls. She is particularly interested in the the spatial aspect of writing, using different areas (such as the web or human skin) to express her ideas.
