Jon Udell is really on a roll. He more or less singlehandedly invented screencasting (I first noticed here), and I guess I’m about the last person in the world to have visited his Walking Tour of Keene, NH, which combines Google Maps and GPS and other assorted magic... in case I’m not the last, don’t you be. Something new is happening here.
And he's right. These things ("Interactive Screencasts ?") are not just trying to approximate radio, or a movie. They mark the beginning of a new dynamic video medium with its own integrity and esthetic and with features that cannot be duplicated, in traditional streaming media. That is, I think the what we see Jon doing in these Screencasts --interacting with a dynamic stream of web-mediated activities--is the real emerging phenomena. The Screencasts themselves are "merely" wonderful records of mankinds first steps in a new medium. (Like the video of Neil Armstrong's first steps on the moon, if you will.) (You have to squint to see this in the play-within-the-play of this movie and its predecessor, in which Jon zooms in and out on the map's scale, even as the animation plays.)
