Anyway, here is a picture I haven't come across before
At the bottom of this page is what claims to be a picture of Beer showing how the controls on the chairs are used. This is the only picture of the control room I have seen apart from the one everyone uses. Though is it me or does the perspective on the picture seem rather weird. Is it some sort of composite of reality and drawing? By this point Beer's beard was longer and getting towards the mad guru look.
