Are you talking about the black item on a bracket that looks like a miniature robot with ears? If so, there is another one (white) like it just below the glass window. It looks like it is a ball that can rotate between the two ears. I was wondering if they were speakers or fans or small a/c's?
I looked back at the picture again and read this.
'His office was a tiny 10ft by 8ft cabin containing a desk, chair and an array of electronic devices including a CCTV system, printer, several webcams and a tangle of wires'
Now I wonder if the cute things bracketed in are actually webcams or are they part of the CCTV system?
I think the printer is up high on desk in the corner by the window with a shade pulled down. There is a roll of paper towels standing up on the desk. There are also some very large looking speakers there too.
I don't see a white box by the big black modem but do see what looks like a cardboard sign up against the window. See where the right upper corner is bent over.
