Mark Twain once said that when your work speaks for itself, don't interrupt. That might serve as a credo for Art and Culture Center curator Jane Hart. Like most of her counterparts at other museums and galleries, Hart keeps a low profile. You won't find her name plastered on the wall at the entrance to the shows she puts together, although you will find her slipping quietly in and out of exhibitions, receptions, and other art-related events all over South Florida, keeping her finger on the pulse of the artistic community she both serves and observes. She's easily the most adventurous curator on the scene at the moment, pulling in such challenging figures as Croatian artist Sinisa Kukec, Turkish-American Stephan Turgel, and regional artists like Michelle Weinberg, Louise Erhard, and Cristina Lei Rodriguez. She's also a pivotal player in the center's big annual fundraising raffle, "Abracadabra," which this year she staged with great flair in collaboration with Miami gallery owner Anthony Spinello.
