Maybe it was because we thought it strange that grown men always seemed to find Miss Piggy attractive, or that no one ever made a big deal about the fact that they were talking to a frog (and not only that, a frog puppet). Either way, there was always something about the Muppets, Jim Henson's odd collection of floppy puppets, that bugged us. The latest exhibit at The Science Place, The Vision of Jim Henson, offers an inside look at the late inventor-director's famed New York workshop, where characters such as Gonzo, Fozzy the Bear, Animal, Bert, Ernie, and Elmo first came to life. The exhibit features interactive displays, working models, videos, behind-the-scenes footage, and a chance for kids and adults to create their own Muppet. The Vision of Jim Henson appears at The Science Place, located in Fair Park, until September 13. Admission is $6 for adults, $3 for children. The Science Place is open seven days a week.
