The Interrotron
Anyone interested in reading about Errol Morris' interviewing technique known as the "Interrotron" will want to check out this link: http://www.markorto n.com/in_brief/Inter rotron.htm
Of course "interrogation" was the first thing to come to my mind; amusingly, the technique/device's name was coined by his wife who wanted to combine the words "interview" and "terror" :D The technique seems cold, hence the name, however it is explained that it helps to relax the interviewees.
Figured I'd throw this out there in case anyone's interested, as I couldn't find anything on Errol Morris' board.
