    Question Snowflake, Christmas Decoration or Tessellation?

    Don't spend too much time on this Challenge as "It's Christmas!".

    Challenge - Starting with an equilateral triangle, can you accurately recreate a Xara-solution to drawing the Koch Snowflake?
    Answer - no-one can as it is infinitely recursive.

    Here is my Snowflake:

    To be clear, I want a set of steps allowing up to a fifth recursion.
    Each recursion simply involves replace the middle third of any current straight line with a path that adds two sides of a (one-third) smaller equilateral triangle:

    Sorry, but this time I'll be too drunk or busy eating everything to even understand the challenge... Marry Christmas to everyone here!

    Marco, just make sure you try a Koch perimeter walk to get rid of the excesses.
