Adult coloring books are all the rage, and now you can make your own version from photos. Chromaldry is an app that turns your photos into black and white line drawings that you can then finger paint to your heart's desire.
Created by Honeycombinatorics, the app converts your photo and lets you mix colors like you're blending finger paints. The results are Monet-esque visions of your street scene, kitty, or selfie.
The app is available on iPhone and iPad for $3.
