Interestingly, Waldo was one of Jim's last puppeterring innovations and was featured on the short-lived Jim Henson Hour prior to MV3D. The tech used to create and control him has been evolved into a number of theme park attractions like Turtle Talk with Crush, Stitch Encounter and the 4D show at Hershey in PA. So Waldo being in the show is kind of just as important as this being Henson's last work: it's his gift to the amusement industry in so many ways.
