I know that the Human-Avian Project website originally had some anatomic schematics on it. Knowing you, you probably have a private library stocked away, but if you need any sketches or inspiration, they're all there.
They used to be on the maximumride.com site, but they've been gone a long time. With one edition of the SOF paperback they came with. Basically it's some memos and newspaper articles on some of our friends at Itexicon, including a pretty nice image I can use to make Itex stationary fakes.
And my Google-Fu is failing, so would you mind shooting me a link?
The mods kinda secrewed themselves over. We used to be attached to the site. It was a home-of-a-kind, and we loved it. We owned the place before the Mods showed up.
Then most of the interesting people all got banned and the site descended into the current mass-produced-dregs depressingness, and all we want to do is kill it. Kill it with fire. ....After trollin' a bit.
But honestly. What did they expect would happen? Don't fuck with anonymous and all that razz.
