Thank you for your comments, everyone! I would like to emphasize that the project is just a proposition made during one Saturday after ThePiachu master thesis inspired me. It wasn't well tested for colisions though. However, I'm happy that this thread is growing and ideas for upgrades appear.
mskwik, thank you for your tests. I didn't think your way: that when the project become popular people may rely mostly on identicon rather that prefix thus they may stop checking it. Now, identicon is made from string made from double sha1 on address. I'm not sure what can be done to make collisions rarer. Maybe you would like to push to github your code?
That would be quite an interesting idea, although it would probably be way harder to implement than random geometric shapes...
Interesting idea. I came across: http://robohash.org/ - cunicula you thought about something like this?

I realize this has no practical purpose, but can you make the identicon into something cute?
More broadly, if you could do QR codes that are shaped like bunny rabbits and pandas, then the whole QR scheme might become more interesting to 50% of the population.

Here you have it: https://github.com/bnowotarski/btcaddr.me
You can use it will litecoin addresses too (even there's "btc" in domain name). To be honest, you can use it with any string as there is no input validation. It just takes a string do sha1 twice and make identicon from it.
Yes, your right. If it would be a part of payment process it's more likely there will be any use of it. Maybe developers will find the idea to be good and include it in a new version of client. We will see...
Oh wow that is VERY COOL. That could go on so many things, right next to your payment address you can show what it *should* look like when you pay.
That's exactly the purpose of it .Is it possible to "scan" the identicon and decipher the address? Like a custom QR code?
No, you can treat it like "visual hash" and it's not reversable.What addresses did you try? You can try it other way:
http://btcaddr.me/[bitcoin address here]
Maybe the form is not working in your browser - which one are you using?

ThePiachu: what do you think about this (https://bitcointalk.org/index.php?topic=122240.0) solving "Partial address collision" problem?
I would like to introduce project I've done after reading ThePiachu's Master Thesis (https://bitcointalk.org/index.php?action=profile;u=34743). In one of sections he writes about "Partial address collision" attack connected with bitcoin addresses. In a nutshell: given a bitcoin address we can generate address with the same prefix. As humans use to read only a few first characters of an address to validate it, malicous user may replace it with generated one and deceive user sending payment.
I believe problem can be solved using identicons. Check the site: http://btcaddr.me/ and let me know what are your thoughts.

I was wondering if anyone from Bitcoin Magazine staff is here? It would be great to have an electronic version of your magazine too, guys. There's a lot of people outside US who are unable to buy it now and would love to read magazine in that form.
