@thecreativeone91's avatar looks like a swastika, as a Jewish person I am offended:
Not really.
Actually this is a common problem with four frame identicons. That's right, they're called identicons, lol Web 2.0.
Probably the worst algorithm is the, at one time, most implemented open source one:
http://sourceforge.net/projects/identicons/
I started with this one myself and noticed while some only slightly resemble swastikas like @thecreativeone91's though some are so blatant to where it's as if they were made for a white supremacist. This is still a common problem regardless of implementation software:

This happens because, as described above, there's an issue with how most people do this. Typically they draw a box in some random or algorithmically defined way, then rotate it 3 more times to create 4 frames. Of course, one could not rotate them, and this was my first attempt at a fix, but weirdly enough it still happens, albeit slightly less often.
Instead the best thing to do is to either create 4 or more random frames within your image, which is pretty intensive (but if you cache it, not a big deal) or what I did was generate 2 or 3 (based on the algorithm) and randomly rotate those to create 8 frames. Believe it or not my solution still sometimes creates things which slightly resemble swastikas, but it's far better than a lot of the solutions out there.
Additionally there's a pretty good solution for WordPress:

It's still neat though and can give some insight into alternative ways to do it than how most open source methods do it, i.e. how to not create swastikas.
