Talk:Moiré error

Is this really Moire?
You know, I have been coming to think about this article and snapshot that I submitted, but I do not rightly know if it is indeed the so-called moire error. I will have to check again through the bugs/limitations in the Doom engine, but I keep thinking that the moire error was an error that flashed the screen black with every other horizontal and vertical scanline.

Can anyone correct this, or confirm that what I have indeed found actually is the moire error?

This picture is most definitely the ceiling tile being extended infinitely...so perhaps this is a long flat error (like a long wall error)?
