Wall Paper Collection

I follow this blog called WebUrbanist. It usually collects series of things. This time it's wallpaper. This is a clear use of design and pattern.

This wallpaper is made up of 4 layers of post-it ike notes. They can be removed, written on and stuck back, but if you take one away, you'll get the next layer and then the next.
THis wall paper is heat activated. By the radiator, or by holding you hands on the design, it will change colors.

The originators of Warping Wallpaper were at least inspired by counterculture themes; how else to explain wallpaper that makes you feel like you’re high, even if you aren’t? Created by Surrealien - an appropriate name if there ever was - these dizzying wallpapers tend to be more artistic than practical.
