Shannon Larratt is Zentastic

Someone sent me this photo recently, but I'm 99% sure they didn't take it themselves (and from the filename I think there may be more in the series), and in any case it's not as if they're replying to my email. So I'm posting it here to see if anyone has any more information…

First, where is this picture taken? From the people in the photo, my thought is Yemen; I don't think it's India or Pakistan (since many people may have that as a gut response). My second and bigger question is about the tattoo machine. It's hard to tell but it looks like a manufactured unit. Who makes it, how does it work (rotary, sprint+electromagnets?), and all that?

If anyone has any good links to alternate designs of modern tattoo machines around the world, I'm interested in seeing them as well.
