Tonight I'm giving a short talk at Eyeo. I'm using it as an opportunity to introduce Ziffer and launch OpenRandom.org.
My first priority is to get the Ziffer out there and into people's hands. If you'd like to get an email when I'm ready to take orders, sign up for the mailing list.
As for the site, I've got a lot of ideas and I'm going to add them as fast as I can. I intend to really beef up the resources section - on deck are source code, Eagle files, links to other RNGs out there, a thorough analysis of the Ziffer's output, and instructions for building your own Ziffer on a breadboard. So, please check in again soon!
