Those of you not happy with the uninspiring walls of your home can do something about it right now with the help of a smart project. Called the IXXI, and designed by Roel Vaessen, Eric Sloot and Paulien Berendsen, these modular connecting system covers will let you cover any wall with the wallpaper of your choosing. You can use any picture you fancy, or a combination of your favorite images, to come up with unique designs. When boredom sets in you’ll be able to replace the existing pattern with anything else. IXXI is basically a combination of cards and connecting crosses (shaped like the letter “X”) and therefore it’s very easy to work with. All you need now is some inspiration and extra cash (prices start at €24.90 and go all the way up to €500) and you’ll be able to completely change your walls right away.
