I ran across this website today about Wilson A. Bentley (a.k.a The Snow Flake Man). Mr. Bentley was one of the first to take pictures of snow flakes and declared that "no two snow flakes are the same."
"Under the microscope, I found that snowflakes were miracles of beauty; and it seemed a shame that this beauty should not be seen and appreciated by others. Every crystal was a masterpiece of design and no one design was ever repeated., When a snowflake melted, that design was forever lost. Just that much beauty was gone, without leaving any record behind."
