關於作者

　　Rufus Butler Seder 是 Lifetiles 的發明者，那是一種用玻璃磚做的壁畫，在觀看者經過時，會像是活過來了一樣；他把這些壁畫裝置在 Smithsonian、 Sea World、Union Station，以及全世界其他的博物館、水族館、車站以及郵輪。他同時也是 Eye Think, Inc. 的創立者，一家使用他所研發的科技來開發製造玩具與禮品的公司。Seder先生目前居住於波士頓。

　　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 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.
