How involved should an artist be in the way a viewer experiences his or her art? We explored the social and theoretical implications of art in November with world-wide art and design phenom Olafur Eliasson, whose exhibit “Take Your Time” is on view now at the Dallas Museum of Art. Judith Garret Segura joined us during the Scene segment to discuss her media-biz history “Belo: From Newspapers to New Media” (UT Press, 2008).
