Illustration of Filippo Brunelleschi's linear perspective experiment for "Human Factors in Simulation and Training" book.

I was going through some of my old books and found this illustration I created for one of the authors, Peter Hancock, in the Human Factors in Simulation and Training book. The original was in color. It was a mixed media illustration of Filippo Brunelleschi's linear perspective experiment. You can learn more about the experiment here.
