If you look at the rotating cube on this page (or this gif, but it isn't looped right), it has a rectangle in the middle formed by part of its outline. However, its dimensions over time don't seem very interesting or useful mathematically or open any new insights. It seems sterile and inert. Why is this? Why are some things in math more interesting or seem to have more applications than others?

What can you possibly do with or interestingly say about the dimensions of the apparent visual rectangle over time based on the actual shape rotating? What could the dimensions of the rectangle as a function of the shape's rotation be useful for?
