VISUALIZING AN INFINITE SERIES - Cynthia Lanius
http://math.rice.edu/~lanius/Lessons/Series/infinite.htm
This lesson uses a trapezoid successively divided in fourths
as a visual representation of an infinite geometric series,
a mathematical concept that is often only treated
symbolically.
Explorations are outlined for investigating a number of
series, and links to related sites are provided.
