At the Solomon R. Guggenheim Museum Maria organized an exhibition of the work of Alfred Jensen, an eccentric visionary painter. She has organized a number of other favorably reviewed art exhibitions, including gallery shows of editorial cartoons, Victorian underwear, art revealing the subjectivity of science, and furniture designed by architects.

Most recently, Maria was the project director and creative consultant for the Totally Kid Carousel, an award-winning public artwork and working amusement ride by sculptor Milo Mottola that features a menagerie of full-scale carousel figures designed in collaboration with neighborhood children. She kept kids, patrons, and carousel aficionados apprised of the progress of the years-long project via web site (www.hoopla.org). Her current long-term project is the development of a roadside attraction featuring The World's Largest Corn Cow, a thirty-foot-tall bovine made of corn.
