title: Preventing generation of swastika-like images when generating identicons
body: <p>I am using this <a href="http://sourceforge.net/projects/identicons/">PHP script</a> to generate identicons. It uses Don Park's original identicon algorithm.</p>
  
  <p>The script works great and I have adapted it to my own application to generate identicons. The problem is that sometimes swastikas are generated. While swastikas have peaceful origins, people do take offence when seeing those symbols.</p>
  
  <p>What I would like to do is to alter the algorithm so that swastikas are never generated. I have done a bit of digging and found this <a href="http://social.microsoft.com/Forums/en-HK/suggest/thread/13ca5fea-80b4-4533-be79-2a07375bfb1f">thread on Microsoft's website</a> where an employee states that they have added a tweak to prevent generation of swastikas, but nothing more.</p>
  
  <p>Has anyone identified what the tweak would be and how to prevent swastikas from being generated?</p>
