Each year between 1991 and 1997,
a calendar of computer-generated images was published,
based on the fractal geometry of Benoit B. Mandelbrot.
Before 1997, the calendar was first done as a
custom edition and then as a trade edition in the following year.
In 1997, the trade and custom editions were the same.
Richard F. Voss edited the calendars for 1991 and 1992
