When a Marlins player hits a home run in the club's new ballpark, there will be an explosion of color, lasers, pelicans and at least one jumping marlin. Miami-Dade County's Art in Public Places Trust approved on Tuesday a proposal for a piece of artwork celebrating home runs designed by world-renowned multimedia pop artist Red Grooms. The piece is still conceptual, but is expected to be 50 feet to 60 feet tall. "I think there has to be some additional surprise elements the audience hasn't seen before," Grooms said by phone from New York. "I'm hoping the marlins will make their appearance after the home run."
