Less, but better There must be millions less of things, less words, less gestures, less of everything. But every word and every gesture will become more valuable. If we can put it all into perspective we will need less things as a result.

Caustic (optics) Caustics made by the surface of water. In optics, a caustic is the envelope of light rays reflected or refracted by a curved surface or object, or the projection of that envelope of rays on another surface. The caustic is a curve or surface to which each of the light rays is tangent, defining a boundary of an envelope of rays as a curve of concentrated light.
