The best presentation I ever saw was done by a colleague of Mikel Harry's at a Six Sigma conference in Frankfurt. The presenter had no ready made slides but he had an overhead projector, three transparencies, a handful of dry marker pens, and an eraser. As he spoke he sketched charts and diagrams to illustrate his points. If an audience member asked a question he was able to provide an answer in both words and with another sketch.
