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.

Still very cool. Do you think you could do one for Litecoin? Is the project open source?

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?

Firefox 16.0.2 on windows 7

-edit-
I first entered your site by your link provided in OP, then used the input field with a random address obtained on this forum (1CoinLabF5Avpp5kor41ngn7prTFMMHFVc). Then I changed some letters and later the whole address but it still gave me the same identicon.

Now I just tried it only adding the address in the URL, like you advised and it workeed. But dont you think it is problematic that the same address gets a different icon everytime I run it? Heck, it does the same thing again now, after Im leaving the tap open for 2 minutes, it returns the same identicon no matter what address I put in the URL.

I just tried it, it always gives me the same identicon, no matter what address I put in. Cookies?

I would like to introduce project I've done after reading ThePiachu's Master Thesis (https://bitcointalksearch.org/user/thepiachu-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.
