Very often we think of layers as something that can be hung on walls or overlaid but layers could also be something sculptural, like mobiles. They seem to live better in homes where not much pattern and color is used, I suppose that is so they don’t get swallowed up by the distraction.  Mobiles sculpture are delicate so they need a clean environment to frame them and let them reign by themselves.   Mobiles by Alexander Calder are very much used by Interior Designers in all types of decor from modern to more traditional ones.
