Mindfields Ahead

We're all pretty well programmed for three dimensions. And other than the occasional Funniest Home Video, we all seem to understand them.

But consider the plight of a flatland resident. He understands but two dimensions. We look down at him, through our third dimension, and interact with his world in incredible ways. We create and destroy structures at will (with our pencil), and even if he could catch us, we can always get away - we simply jump up (we've disappeared!) and put our feet down somewhere else (teleportation!).

As we are to flatland, so are 4-dimensional creatures (those who natively interact with time) to us. And while we may not be able to properly perceive space in 4D, it can be a lot of fun to try.
