Many years ago, the computer graphics community discovered some amusing techniques for deforming spheres to create flexible models ofcomplicated solid objects.  These so-called "superquadrics" were then widely used for shape modeling in graphics as well as shape recognition in machine vision.  In the early 90's, I started looking at complexifying these shapes, noting their relation to the "Fermat Equations" familiar from Fermat's Last Theorem.  The outcome was a family of graphics methods for interacting with the resulting complexified surfaces and a computer animated Siggraph film entitled "Visualizing Fermat's Last Theorem."  A decade later, it was noticed that the Fermat Equation methods corresponded exactly to those needed to create representations of the Calabi-Yau spaces embodying the "hidden dimensions" of string theory.  The resulting images were included in Brian Greene's 1998 best-seller "The Elegant Universe" and since then have appeared in literally hundreds of other scientific an artistic venues, including Scientific American and a 2003 NOVA television special on string theory.  (NOTE: This talk will have lots of pretty pictures and animations, and the only math you need to know is the equation of a circle!)
