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!
