A handful of popular blogs have evolved into books, but Grand Text Auto – a blog about the potential of digital media, from literary Web sites to experimental computer games – is the first to spawn its own gallery showing. The exhibit, which runs Oct. 4-Dec. 15 at UC Irvine’s Beall Center for Art and Technology, brings the spirit of the blog to life by showcasing cutting-edge works by the blog’s six contributors and their collaborators. The blog-meets-reality showing includes projects like a literary game played with 3-dimensional text and an experimental novel distributed around the world on mailing labels.
