Talking about the geometry of space raises a good point too. For example, how the shortest distance between 2 points on the outside of a sphere like our earth, is not a straight line. Seems counter intuitive based on or everyday experiences and perspective, yet we know its true. Well to put into intuitive terms, a tunnel through the ground is a way to make a straight line so cars and trains to don't waste time going across the bumpy curve of the earth. Sort of like the earth curve is 2D, but the tunnel cuts through the 3d space of the earthsphere...a short cut for sure. About flatland, sure it is a problem, "penalty of projection", there are a lot of penalties. About the squares point of view, he knows he has 4 sides, triangle knows he has 3. But they don't understand the area, but they can guess, just like they have 2D houses and can go inside and explore the area. The apple would be weird sets of lines not "shapes" necessarily from the square's view point. honestly for 3d folks, it is similar. We see actually in 2d and as the shape changes we understand with depth perception what is happening in 3d. Folks without depth perception have problems with our 3d world for this reason. Only by touch can we really "see" the 3D cube. Likewise this Tessarect is actually being shown on a 2D vid screen. Our depth perception creates the optical illusion that it was a 3d nested cube object. Ricardo
