Mathematica is an exhibition presented by San Francisco's Exploratorium museum. Although the physical exhibition concluded on May 5, 2002, some online material about the makers of Mathematica is still available for browsing. Well known modernist designers Charles and Ray Eames created the exhibit 40 years ago to make math fun. The most interesting resources on the Web site are the three Real Video Web casts. These 75-minute presentations focus on architectural design and offer different perspectives of the Eames's work. The first Web cast starts with poor sound quality, but it improves after the first couple minutes.
