Projections are the best way to understand higher dimensions. Our eyes see only in 2D, yet we unconsciously infer 3D from the 2D images. Similarly, a 4D being would see in only in 3D, and infer 4D from it. Since we are familiar with 3D, it is not difficult to understand what the 4D being sees in its retina. From there, we just have to deduce 4D depth in order to "see" in 4D.

By applying dimensional analogy to such 3D projections of 4D objects, we can intuitively derive many properties of 4-space that are otherwise obtained only through painstaking mathematical analysis and deduction.
