Rather than having empty building walls covered with advertising or at best with ivy, why not install the Reviwall and turn your wall into a vertical vegetable garden?
Some inspired Italians have set one up in Revigliasco, a small town near Turin, and it just looks magnificent. Check out the photo gallery on the website of La Stampa newspaper.
Clever also the name, as it is not only a Revi[gliasco] wall, but also alludes to this pleasant "revival" of urban walls.
