This application generates a dummy image like Github and Stackoverflow do when there is no profile picture added by the user. It is called Identicon.

To run this open your elixir console and type Identicon.main("user_name")

If available in Hex, the package can be installed by adding identicon to your list of dependencies in mix.exs:

def deps do
  [
    {:identicon, "~> 0.1.0"}
  ]
end

Documentation can be generated with ExDoc and published on HexDocs. Once published, the docs can be found at https://hexdocs.pm/identicon.
