May 4, 2011 was the UPenn Art of Research Graduate Symposium.  
I gave a talk entitled "The river banks of Ellsworth Kelly's <i>Seine</i>" 
relating a painting I saw in the Philadelphia Museum of Art to a statistical 
physics model called gradient percolation.  In this folder currently is my 
PDF slides.  I hope to put in some Mathematica notebooks and images at some 
point in the future.
