Toby Howard created the storyboard and developed the supporting text for this section of the slide set. Jenny Morlan, Assistant Professor of Art at DePaul University, generously gave of her time and talents in the development of this section of the slide set.

The figure drawn in slide 3 uses the data points of Newell's teapot.

Many thanks to Steve Cunningham and the Winter '92 "Environmental Graphics" class at DePaul University for viewing these slides and making many helpful suggestions.
