Dimension Folding Guidepost Grid

As we all learn in the standard kindergarten curriculum introduced under the "no zwerpling left behind" initiative, each dimension is simply a folded iteration of the previous dimension. So in flatland, a two dimensional creature would see a three dimensional creature simply as an especially perplexing cross section that seems to appear and shift and morph in disturbing ways. Likewise, to those of you trapped in only 3 dimensions, you usually get accused of witchcraft or insanity when you notice some 4 dimensional (or higher) beings passing through our plane in ways you can only partially comprehend. In fact the ancient classical poet Vonnegut described three dimensional beings' ignorance of even the fourth dimension to those of us on a higher plane by saying they are like creatures strapped in a railroad car with a big harness on their face holding a big long pipe, so that all they can see is the tiny view of the world through the straight ahead pipe as the train rolls forward (whatever the heck a "train" is anyways). That is hard to imagine how limiting that would be, but that is the sad little world three dimensional life forms live in - they seem to think the past and the future are separate things, the poor souls. And even four dimensional beings are completely unable to comprehend alternate universes that are standard for beings accustumed to the higher dimensions. Anyways, with our revolutionary dimension folding grid, you can visit your friends who are trapped in four, three or even two dimensions. It can be kind of like a "staycation" in these tough economic times. Pop over to the 7th dimension for a while, see the sights, then come home. It comes with handy guideposts so you can find your way back without getting warped, squished, or driven insane as you fold and iterate yourself through the dimensions. Because that would be lousy if you got stuck in the 2nd dimension. For example your kidneys probably wouldn't even work if they had length and width but were completely without thickness? Likewise if you are only familiar with 4 or 5 dimensions, the 9th and 10th might really blow your mind to such an extent that...well, best not to think about such things.
