Good Afternoon, As part of an unrelated forum project that I'm building, I put together a project to use a SHA hash to create robot-avatars, called RoboHash. (RoboHash.org). This is similar to the identicons that are currently being used in FreeTalk, but it's designed to be easier to remember than a Identicon, which is somewhat random, and IMO at least, hard to remember.
The code is at https://github.com/e1ven/Robohash, and you can use it under BSD license if you'd like. The images are CC-BY 3.0. My code is python, but it's basically just overlaying transparent PNGs on top of one another after doing a modulo on bits from the SHA hash. In any event, if it's useless to you, feel free to ignore, but since it was in part inspired by Freenet, and I am releasing it as OSS, I figured I should give you the chance to use it if you want ;) -CPD
