No two snowflake designs are alike, but many represent fractals in that the branches of a snowflake spawn their own side-branches, and so on. The snowflake could continue on like this for an eternity, growing the size of Earth itself, if it weren't to stop accumulating moisture and, eventually, melt away.
The most famous fractal snowflake pattern is known as the Koch snowflake, stemming from one equilateral triangle forming another and another and another. This was one of the earliest fractals described.2
