My artistic sensibilities came to life while imagining the two-dimensional Flatlanders discovering the third dimension. How could these creatures live, play, and build a society like our own? How would the fourth dimension appear to us, and how might we appear to higher-dimensional beings?
Could the shape of our universe be curving in some higher dimension? Could someone in a fourth dimension be present, like you, dear reader, could be to our blockhead, without being visible in our three dimensional world?
