Do you guess what you see here?
It's the graph of the 8-dimensional hypercube which is drawn as 16 copies of the 4-dimensional hypercube (or tesseract).
All $4n$-dimensional hypercubes can be drawn in the same way, yielding a series of fractal patterns.
I wonder if this kind of drawing can already been found somewhere, and if it has been generalized for other than $4n$-dimensional hypercubes -- and possibly hypertetrahedra?
