Drawing on the Right Side of the Brain has remained the dominant book on its subject, used as a standard text in many art schools, and has been translated and published in many foreign languages, including French, Spanish, German, Polish, Hungarian, Chinese, and Japanese.
In addition to teaching drawing workshops around the world, she has also done business consulting with major national and international corporations to enhance creative problem solving.

To avoid the so-called "location controversy" (how the two major cognitive functions are distributed in the individual brain depending on handedness and other factors), she termed the modes "L-mode" and "R-mode."
