About the Author: Rufus Butler Seder is an American inventor, artist, and entrepreneur, best known for his invention of “scanimation,” also called barrier-grid animation or picket-fence animation. Scanimation animates static images using vertical lines on transparent sheets, creating the illusion of motion when moved. Seder’s children’s books, such as Gallop! and Waddle!, are popular for their page-turning movement.
