[PSTUM-list] Resources on Chalkboard Technique?

Yes, the Preparing and Supporting Teachers of Undergraduate Mathematics (PSTUM) listserv is still operational! I have a question that, I think, is perfect for this listserv. Do you know of any good resources on good chalkboard / whiteboard techniques? Ones worth sharing with grad students just learning good boardwork? Steven Krantz has a good section on this subject in his book, How to Teach Mathematics, but it doesn't include any visual examples. Know of any good resources along these lines?
