Every time I see that picture, while very well made, it makes me think of Ray, from 'Ghostbusters', with one of those goggle sets from the cartoon show.
I'd like to think that, seeing as, right now, we have the technology to control cockroaches, any mind-controlled Aliens would have much less obtrusive technology.
Then again, I also like to think nobody would be crazy enough to try doing so... What would be the point? Just exploit their biology for new weapon-applicable patents and create new technologies with them all.
