I believe "Art" could be defined as
             "the conversion of a physical item, movement or actions into beauty."

One of the most interesting concepts on creation of art is how a movement with
simple brush strokes, colored oils or materials, tight wound strings, or even
stacking silently still rocks upon the ground can be turned into beauty in a single
moment where only existence was before.

The most incredible concept in the art of rock stacking is that these static and
silent rocks can be transformed into a thing of beauty only to be returned to the
ground in a heaping mess of chaos before the end of the art. This art form leaves
only the a memory, a few static images or, if you are lucky, some life inspiration
from what just occurred.
