Sharing something I had taken a couple of years ago. I setup a small 3" glass bowl filled with water and started adding drops of oil of different viscocities - peanut, sesame, clarified-butter, etc. I had two small flashlights as sources of light from the sides of the bowls at opposing ends, 180degrees. This is one of the many images that I took, probably resembling a new planetary system taking shape. EVOLUTION of sorts !!!
