As Kalley explains each part of her invention, the drawing comes to life even as its overall purpose becomes less and less clear to her dad. It is only when Kalley explains the machine’s final component that her master plan to keep her dad from commuting is revealed. THE STORY BEHIND THE STORY --------- So, there really is a ‘Kalley’. She really drew a machine. Her dad couldn’t build it. So they made an app out of it instead. Full story at kalleysmachine.com. FEATURES ---------------------------------------- ► PLAY WITH MACHINES!
