Jenise sez, "I work for Kiva Systems, a small robotics company in Woburn, MA, and the bots are amazingly fun to watch. A few years ago, one of our interns shot this video of the bots dancing to the Nutcracker Suite, and I thought it would tickle your ample sense of whimsy."
Ample whimsy: tickled.
(Aside: Whenever I hear the Nutcracker Suite, my stupid brain insists on supplying the lyrics from the "Smurfberry Crunch" breakfast cereal ad: "Smurfberry Crunch is fun to eat/A Smurfy fruity breakfast treat/Made with crunchy strawberries/They taste so sweet and [garbled]/Very fresh and very true/And very very Smurfy blue!")
