Maybe this has been discussed to death already... The last thing I heard was Muta said Boogie could have just turned his camera. My thoughts are only slightly different.
This was Boogie's backdrop before he "took it all down"
This is Boogie's backdrop post-removal

He's sitting right around where his play button used to be (note the plain brown wall to the right); the brown shelf behind him, and everything around it is gone.
However, you can still see a little bit of the black shelf that holds his puppet in the lower left corner, and it looks like something is on top of it (maybe that lamp in the 2nd image?).
I think Boogie just moved his desk closer to the wall to tighten up the camera's view, then moved all his shit out of frame to create the illusion that he got rid of it. I don't see any reason Boogie had to move his desk unless he was hiding something. Why go to the effort, when Boogie has
never been about effort?
