** Works In Progress **

The following projects have been posted in various stages of completion; inasmuch as they represent ongoing research and development, they are likely to change radically from one revision to the next. I offer them, however, partly as windows (you can see what I'm up to) and partly as doors (I very much welcome your comments, criticisms, worries, footnotes, and so on; if your web browser supports mail links, you can reach me directly from here).
