I found it interesting because my high school just recently hosted a math tournament, and I wrote the test with the last round involving this very subject of perfect shuffles. (I guess I would fall into the category of math geek readers, then :-p.) I agree that there are very cool things that happen with vertical symmetry; for example, when your stack has a number of chips that is 1 less than a power of 2, halfway through the shuffling, the order of the chips will reverse entirely. (I think I have that right, but I’m not sure… your shuffle is called a perfect inshuffle, but the type I dealt with is called a perfect outshuffle.) Anyways, if you’re interested in the kind of things I found, feel free to e-mail me, and I’ll e-mail you back with my findings.
