I thank David Donoho for his introductory lecture on wavelets. Francis Muir made us all think in terms of a Z transform formulation. Martin Karrenbach introduced me to xtpanel and asked many useful questions. Ray Abma reproduced for me the picture of Steve Cole which he used in the last report. And, of course, my compliments to Steve Cole and Dave Nichols for writing xtpanel; my project would not have been as much fun without interactivity.
