Re: Wrinkled Shirt
Madeleine L'Engle in the science fiction-fantasy novel A Wrinkle In Time uses a tesseract as a way of traveling. The easiest way to understand how a tesseract would help with travel is by analogy. Imagine a two dimensional creature, stuck on the surface of a three dimensional cube. Traveling across the surface of the cube would take more time than cutting through the center of the cube, as a three dimensional creature might. Traveling by "tesser" or "wrinkling" allows the children of the book to be transported to places unreachable by normal means of travel.
