Earlier quoted context omitted.
GitHub now owns the octocat art.
You guys should seriously think about allowing other projects to use the octocat when the projects are associated to github. it would be a nice way of everybody having a common "icon", much like twitter has the bird. I know people can link to github, but that's not always possible (mobile apps?) even though people use github..
I think a good solution would be a new open license logo, like the Minefield logo as opposed to the restricted Firefox logo.
