Today we saw this out the window. It started a discussion about how the (actual) sky looked "fake." We have gotten so used to seeing manipulations, special effects, Photoshopped pictures, and all manner of fakery, that an unusual-looking real event seems like it must be some sort of a con. Like it is the last straw that proves we are really living in a manufactured reality like in The Truman Show.
But this was a lenticular cloud over Mt. Hood. It stayed perfectly lined up like that for a few minutes, then it was gone.
