There is indeed an IF Art Show again this year; deadline, May 2.
Play This Thing! is reviewing Photopia (not my review, this time, but I thought people might be interested).
Jeff Nyman has another interesting post on his IF classes, this time on why his next class will be using TADS 3 rather than Inform 7.
Grandtextauto points to Hypertextopia, a program especially for the creation of “axial” hypertexts — there’s one main line of narrative to follow, with what might be considered footnotes, expansions, or embellishments. I wasn’t thrilled with the couple of examples I briefly looked at, but it represents a possibly-interesting alternative take on how hypertext design might be done.
