This meat is like shoe leather! On Fri, Apr 28, 2017 at 9:57 AM, Bill Gosper <billgosper@gmail.com> wrote:
Actually, close questioning by Mike Beeler jogged me to remember what is probably a big clue: Somewhat prior to the creeping, I noticed on that shoe the grommetoidoid (occulted, opposite the circled one) in gosper.org/shoe.png can now freely pivot. After the next [shoelace] creep cycle, I'll try gluing it.

Better idea: When the two ends get sufficiently uneven, fold the long one double, and treat it like a single strand. At least with the doubly circled thumbnail mod, this has the neat effect of untying _completely_ when you pull both ends at once! I.e., there is no residual overhand starting knot left to undo. Bonus: You have to pull really hard, making a disastrous-looking snarl before it pops, to the surprise of onlookers. --rwg
