I think we should make one. It'll be useful at Defcon, HOPE, and a bunch of other places.
I'm hoping Alison/the community team thinks this is a good idea and can assist me in making sure it dovetails with the rest of their efforts in https://trac.torproject.org/projects/tor/ticket/24497
What I probably _can't_ do is graphically design it in a way that meshes well with any other materials we have. I talked with Steph in December, she may be interested in this?
I've started a pad to start this process and cover what I think should be contained: https://storm.torproject.org/shared/kOwybHn5VZdMRDm1L-kQg6P-DMC3G2w0Zn5XLQ1Z...
We have to fit everything on front-and-back on a standard 8.5x11" sheet so we'll have to make some tough decisions about what we include and what we don't, but this is a start.
