Scan This Interactive Kids' Wallpaper to Find a Bedtime Story

French home improvement retailer Castorama has come up with a fabulous idea for kids' bedrooms: interactive wallpaper that you can scan to find a bedtime story.

"Magic Wallpaper," designed by TBWA/Paris, features 10 different characters conceived and designed by the agency. Each of the printed characters is a digital marker, and when you scan it with a tablet or smartphone you can download a story about the character. To make things even more interesting, you can scan two different characters and combine them to get a whole new story.

The Magic Wallpaper app comes with two reading modes: an audio version with the voice of a storyteller, as well as a text mode with sound effects available by clicking on certain words. Each story lasts about five minutes.

The app can work in airplane mode in order to limit the exposure to waves, while a night mode with fainter luminosity is also available.
