The girls and I went to the Jim Henson Legacy exhibition that just opened in some basement gallery at the Smithsonian, so you don't have to. Seriously, just put it in a book. Or a file folder, what a pointless hodgepodge of sketches, posters, storyboards, and three video screens, all sprinkled with the odd Muppet-in-a-vitrine. For a seemingly kid-oriented show, almost all the material is uninteresting--or because it's paper hung high on a wall, literally unviewable--for shorties.
Henson's movies are almost completely ignored. Of the three monitors in the exhibit, one is showing early Henson commercials starring puppets; one is showing a split-screen view of Time Piece and its rudimentary storyboard; and one is showing a biography of Henson by The Biography Channel, the show's sponsor.
If they'd had Time Piece on the full screen, it would've been the sole highlight of the show. Instead, that honor [sic] goes to the storyboard for this early, trippy stop-action animation for the number 12. Not because the storyboard's interesting, but because it reminded me of the clip's existence.
