Published last fall, "Gallop!" introduced the amazing technology called Scanimation and took the children s book world by storm. It became an instant bestseller #1 on The New York Times children's list. Now "Swing!" does for kids what "Gallop!" does for animals a boy rides a bike, a girl kicks her soccer ball, a swimmer cuts through the water, and a skater pirouettes on ice. The effect is joyous, magical, mesmerizing, and taps into the the endless fascination that children find in watching other children. The second book created by Rufus Butler Seder, the inventor, artist, and filmmaker who developed Scanimation out of his obsession with antique optical toys and other pre-motion-picture illusions, "Swing!" uses "persistence of vision" and a patented state-of-the-art multiphase animation process to create astonishment. There is nothing else like this unique, patented technology that literally inspires wonder. The images burst with activity, and adding greatly is a happy, rhyming text that captures in words the pure energy of the figures in motion. You can't put it down."
