Identicon
From wikipedia:
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.
Usage
Assuming you have Elixir installed on your system:
$ git clone git@github.com:alephmelo/identicon.git
$ cd identicon
$ iex -S mix
It will enter the Elixir interpreter.
iex(1)> Identicon.main("test")
:ok
