Update: Greg adds, "Erik did not do the music–that’s Creative Commons work downloaded by Terran McCanna, who did the animation and additional website artwork and graphics. Astrid helped with research and photography. Alexandra is blogging as Hope Hodgson, and we invite contributions of artwork and dreams of the far future. Erik did a Flickr photolog which we’re also using on Moo cards we’re handing around at Worldcon. Plus buttons, of course."
