(It's a mechanical arm rig she found laying around somewhere)

Apparently Gunnerkrigg Court: Orientation (the book containing the first 14 chapters of this comic) is now available in US comic shops. There may have been sightings outside of the US, but I don't know. If you had one ordered at a local comic shop you might be able to pick it up. There is a thread in the forum for people who have managed to find a copy.
As for availability outside of US comic stores; I'm sorry but I do not know. I'll post more when I know more, and I should maybe make a banner or something when the book is available.
