A couple of months ago I started walking down the path to a collaborative project about a Crab. Unfortunately the project didn't make it out of the very early stages of exploration, but a few good ideas came up. Here are some early pages of that exploration. Apparently Leonardo Da Vinci used to write backwards so people couldn't steal his ideas about corkscrew flying machines, similarly, I write in an illegible scrawl that only I can understand. And draw with pictures that only vaguely resemble ideas I had at the library. Sorry.
