Organized by SITES and The Jim Henson Legacy, the traveling exhibit Jim Henson’s Fantastic World opens tomorrow (Saturday July 12th) at the S. Dillon Ripley Center International Gallery, featuring artifacts of the much-missed imagination and visual thinking that brought us the muppets, Yoda, and The Dark Crystal. The Ripley Center can be a bit hard to find if you’ve never been there before, as it’s mostly underground; just look for the copper-domed kiosk sitting between the Castle and the Freer Gallery (map). I’m hoping to see one of my boyhood crushes there, Kira the Gelfling. Rawr.
