This “Heritage Art Collection,” image is from the chemistry of concrete German bunkers on the high bluffs overlooking Omaha Beach, Normandy, France, place of the D-Day invasion by American troops.  All that came to mind as I saw this crystal grow, was the carnage and impression of ascendency of the human spirit during the height of battle. One sees, relates and interprets according to what is anticipated, especially with knowledge of the material being crystallized.  Nothing mystical, just psychological, empathetic and very human!
