A course on interactive book design for the iPad, a topic that wouldn't have existed two years ago, is now being taught by Stacey Williams-Ng at the Milwaukee Institute of Art & Design. Even Stacey seems surprised that her love of illustration and knowledge of graphic design have combined into a new career for her, interactive storytelling. She loves putting brush to canvas, which is how her children's books begin before they're photographed or scanned into the iPad—where she actually uses an app to create apps. Her business has blossomed into a publishing company (Little Bahalia) that's dedicated to creating interactive children's literature. We join her at her home studio in Milwaukee where she's animating her latest book, A Troop Is a Group of Monkeys, destined for the iPad. Quick quiz: What is a group of bats called? Find out during this installment of the lynda.com documentary series The Creative Spark.
