Hm...now that may be a different matter...if you're allowing something as small as a 3x3 grid with a hole in the middle, I may have time to come up with something after all. In fact, I've got an idea for something that would work (though only with one knight's tour forming a sensible narrative, not both)...which I can probably have done by some time next week.

A larger knight's tour comic might still be fun to do, too, but that'll have to wait till I'm done with my dissertation...
