A narrator builds a wireframe cube in fractalspace, a virtual environment where the map repeats infinitely. Because the same cube appears over and over across copies of the space, the repetition manifests as a tesseract, a four-dimensional hypercube.

I'm building a 4D cube here in fractalspace where the map keeps repeating itself. I'm going to start by building some of these cubes up and making a wireframe. And you can see as I'm doing it, you see myself on the other map over there also building a cube simultaneously as me. And I could go to that cube and he can go to that one. So I'm just going to keep building this cube here, and when it's done, you're going to see a tesseract in fractalspace. ...where since the map repeats itself over and over again, you see this cube over and over and over again, and it's infinite. You could just keep going in and it's the same cube. Yeah.
