Pebbles
We have all seen unusually shaped pebbles or picked up a pebble and cast it into a lake or pond. The concept of pebbles comes from the infinite shapes they are formed into either by breaking off a larger rock or being continuously washed over by water. They hold an imaginative quality that allows you to see common everyday shapes such as a heart that brings warmth to our hearts or the shape of an island/country. You may see nothing at all but just enjoy looking at the abstract shape and feeling the smooth surface.
