From an interview with Rachel Rosenthal, a Los Angeles performance artist, in the 1991/1992 issue of Mime Journal, published annually by Claremont College, in Claremont, California:

The pieces that I am working on now, after having gone though nuclear power and other things like toxic waste, the animal question, the human brain, are more and more concerned with "the big picture." You have to begin to get a sense of time that goes beyond human time. So I'm working now on a piece that deals with plate tectonics. To me, it's a sexy subject. The piece is called "Pangaean Dreams," Pangaea being the supercontinent that existed 250 million years ago and out of which the continents drifted to form the geography we have today. I performed the first version in Tucson, Arizona, and I was surprised and deeply hurt that a critic who gave me a good review said something like, "Well, it may not seem like a real exciting subject, but the way Rachel plays it, it was." What can be more exciting than plate tectonics?
