One day each year, artist Edward Tufte opens his Hogpen Hill Farm in Woodbury, Conn., and its 234-acre landscape sculpture fields to the public. It is wild, whimsical, grand, and incredibly beautiful, with sculptures ranging from stainless steel surfaces reflecting every nuance of light, to lacy stone walls and silent boulder megaliths.
Tufte is also known as a genius of data visualization, professor emeritus of political science, statistics, and computer science at Yale, an author of books on information design, and a hater of PowerPoint.
