Fisher-Price's Little People barnyard gets a big upgrade for 2013. The barn is actually moving onto the iPad — literally! The new Little People Apptivity Barnyard ($40) combines a barnlike plastic case with a free companion app that responds to the actions of the included figures and accessories. Move the pig from the barn to the mud, and you'll see his footprints behind him. Open the barn door, and all of the animals will appear to be running across the screen. Available for use both when the iPad's on and off, the set could redefine how tots interact with technology.
