When we built a new side yard patio, the location of our air conditioner was less than ideal. So I smashed old plates, cut up old mirror and pieces of stained glass, to make a two sided mosaic screen that picks up the colors of the surrounding hostas.

The cream colored grout is sealed, old fence posts were used as the ends and the whole thing is movable in case we have to get at the air conditioner. It's much nicer to look at than the grey turbine.
