Hypercubes2 T-Shirt

You can see how 2 squares displaced and connected via a third dimension make an ordinary (3D) cube. And you can see how 2 cubes displaced and connected via a fourth dimension make a 4D hypercube. Etc. .. up to six dimensions. Hypercubes are handy for mapping binary codes (N-dimensional hypercube for an N-bit code). Here, the integer value of each code C gives its horizontal position, and the integer value of the code C written in reverse gives its vertical position. Codes that differ by one bit are connected by lines.
