Swopbots were a concept proposed to Nickelodeon through Film Victoria in 2006. These Wallpapers (or Desktops) were designed to intelligently interface with the functions of the mobile phone. The Wallpaper changes or animates in response to triggers including random events, times of the day, battery and signal levels and phone events. For example a character may become progressively sad as the battery level on the phone diminishes while the sun moves across the sky as the day continues. The effect is a continually changing and seemingly ‘living’ character and environment on a phone desktop.
