* Identicon

Identicon generator example in Elixir

- Identicon :: An Identicon is a visual representation of a hash value, usually of an IP address, that serves to identify a user of a computer system as a form of avatar while protecting the users' privacy. The original Identicon was a 9-block graphic, and the representation has been extended to other graphic forms by third parties.

  def main(input) do

    input

    |> hash_input

    |> pick_color

    |> build_grid

    |> filter_odd_squares

    |> build_pixel_map

    |> draw_image

    |> save_image(input)

  end
