The official website for Creating Interactive Fiction with Inform 7 is now online. This also means the book's example game, Sand-dancer, is released: it can be played online and downloaded. As previously mentioned, this is a real interactive fiction that you'll build line by line as you progress through the book. Versions of the story as it exists at the end of each chapter are on the website for those who aren't up for quite that much typing.
Amazon lists the book as shipping tomorrow, which means it's quite possible some of you will see it in print before me. On a related note: if anyone with the ear of an audience who might be interested in this sort of thing is interested in a review copy, let me know.
