This is pretty amazing and I hope it will be on sale soon. Dutch designer Jonas Samson came up with this light-emitting wallpaper.
it’s possible to use a two-dimentional flat surface as light source instead of a 3D object.
As long as the wallpaper is turned â€˜offâ€™, it is indistinguishable as a source of light. Instead, it is just what it appears to be: wallpaper.
