"Oh, yes: I finally came up with a recurrence relation suitable for creating a Keplerian octagonal tesselation."
this guy's website, quadibloc, includes more complicated shit than i will ever understand in my entire life. but boy are the images cool! maybe one day i will take the time to read and semi-comprehend the explanations of map projections, tilings, the jewish calendar, CHESS, the inner-workings of computers, how telescopes work...........or ill just look at the pretty pictures.
and good luck navigating the site, it's as much of a labyrinth as THE HUMAN MIND!!!!
