Imagine a room wallpapered with post-it notes. In reality designer Duncan Wilson came up with this idea and the concept even won awards. He calls the concept Pixelnotes and explains it as:
A wallpaper consisting of four layers of varying grey tones on a bright primary backing. Each layer is perforated in a grid format and backed with a tacky adhesive similar to ‘post-it’ notes. Pixelnotes is inspired by the way we work within a space. The walls become functional, an integrated noticeboard that documents our activity within the room. Pixelated formations and shapes develop according to our patterns of use.
