Coloring outside the lines is one thing. Coloring in 3D is another.
Disney Research has developed an augmented reality coloring book app, Disney Color and Play, that lets you color and watch characters on the page come to life. You don’t have to replace a crayon with a stylus; the app uses a digital overlay that “enhances engagement,” according to the company
Unfortunately, you can’t use this app with just any coloring book, though. You have to use it with Disney Color and Play coloring books or individual pages you can print out at home.
