How Do I Generate Random Identicons?

Question

I am looking for the most basic way to generate random "identicons", with no regard for a user email/ip address, etc.

Answer 1

Wikipedia lists a number of implementations that allow this:

• http://en.wikipedia.org/wiki/Identicon#Implementations

You could seed a library call with whatever random data you want.

Answer 2

I wrote this the other day: http://jsfiddle.net/pHv6W/

It will generate a random hexadecimal hash and display an identicon and a monsterID from gravatar.com

Answer 3

I made a jQuery plugin to solve this problem: You just need to supply the hash value.
