And that's why I personally have trouble picturing euclidean space, for every time I graph something with right angles, I know the graph is subtley warped by the mass of the pencil lead I'm laying down, yea, even by my own mass as I might move about trying to view the graph. Those right angle just don't remain right angles. I'm amazed by anyone who can tolerate the notion that they do.
