A developer by the name of Don Park has created a new way of identifying users. His method turns their IP address into a unique image.
Within his blog, each commenter gets a cool generated image to represent their identity. Don has provided people with a simple webservice to use on their sites, if they want to use his technique as well. His creation was mentioned on CodingHorror this morning along with a port of the code to .NET 2.0
I don’t really have a use for it just yet, but it sounds interesting, for sure. I like that it somewhat hides the identity of the person while still uniquely tagging their connection.
