** 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).
