I don't rule out the possibility of someone having once hidden an image in some artwork for mischief, but it's unlikely. These aren't young mischievous brothers doing the paintings, they're generally older, trusted brothers who take their work seriously.
Apog, I haven't really noticed any indication that anybody believes there is some kind of conspiracy.
You must not have read the post on the top of this very page then. This pareidolic bullshit does lead directly into the notion that the WT is trying to program people with images, and you guys can't even agree what you are seeing. I'm embarrassed to be on this forum right now and will absolutely speak out when I see this foolishness, regardless of what you guys feel about it.
