Will look up Bret Victor --- thanks!

Unfortunately, while I like emacs-style keyboard bindings in Mac OS X, I prefer to use a stylus and often write things out by hand and use handwriting recognition to convert to text (hence my interest in visual programming languages) --- very much envied a co-worker (who was one of two folks I've met aside from TeX conferences who had read TAoCP) who just started it up at the beginning of the day and got all his work done in it during the course of the day.
