While walking my dog Niko tonight, I was talking to him, as usual. I was just babbling. I was also mumbling. I thought there should be a nice portmanteau word combining babbling and mumbling. Both end with “bling”, so the first three letters have two choices: m/b, u/a, and m/b. That situation can be nicely drawn as a cube. Here are the axes, and the results. Of the eight possibilities, two are already words: in the back-lower-right corner (the cube we can’t see) is bubbling, and in the near-lower-left is bumbling. But the one I like best is bambling. I don’t know, it just feels right. To see a larger view of this image, and another image of all the cubes isolated, click here:

When I was drawing these pictures, it occurred to me that I was also rambling. So for extra credit, draw a 4D cube (or tesseract) that has all 16 combinations of babbling, mumbling, and rambling.
