Lots more about e-poetry at ELO (Electronic Literature Organization, includes links to their collections 1 and 2), The Electronic Poetry Center, Peter Howard's Hypertext Poetry and Web Art, and Poems that Go, a now-defunct magazine. Or try The Shape of a Box, a youtube lit mag, or Here Explodes My Giant Face, which publishes poetry videos. And there are (or were) at least three literary magazines on Twitter: Baby Trotsky, Form.Reborn, and Outshine.
Perhaps related in some way to digital literature, perhaps not: altered books / book-related-art by various book artists, Thomas Allen, Ellie Brown, Brian Dettmer, Zach Gage, Guy Laramie, Lori Nix, Robert The, Miriam Schaer, and Tona Wilson. Books that destroy themselves: Zach Gage's Antagonistic Books; self-blackening book by Camille Leproust and Andres Ayerbe.
