Molecular variation!

They say no two snowflakes are the same, molecularly speaking, (though they can be almost identical) The difference comes from the molecular arrangement of the extensive network of water molecules as water freezes. It is amazing how a slight twist, a slight tilt in the arrangement of the same number of water molecules creates this vast variety of shapes and patterns.

These are four of about thirty flakes that landed on my woolen glove :). Each beautiful, each magical, each unique.
