nd to those changes (see Greenberg, Fitzpatrick, Gutwin and Kaplan 1999 for further discussion). At the same time, several of us developed 'web-cam software' that could automatically take periodic snapshots (e.g., an image that changed every half-minute) of a person and post it as a file on a web site and thus accessible by URL. While such systems are in fairly regular use (e.g., Lee, Girgensohn and Schlueter 1997), what was interesting is how we bootstrapped and adopted it to our use. We should mention that our adoption of the system was emergent: we had not planned or agreed to use this system between us, and no one helped set the system up ahead of time. In the beginning, one person (Kuzuoka) built a version of this system, and used it to create a personal web page of himself i.e., the page included an individual periodic snapshot plus textual description. That system was not passed onto others because it used a mix of hardware and software difficult to replicate. The next version
