Apparently I've been tying my shoelaces wrong

TED talk here.

And while I'm on the subject, I've always wondered whether the Cold War "secret communication" method illustrated at the top (with examples that wouldn't work on the illustrated shoe...) was real, or just something that John LeCarre made up for his books.


  1. I've been using the Ian Secure Shoelace Know for maybe 25 years now, and have a few members of my extended family onboard. Haven't had a shoelace come undone in all that time!

  2. According to my nephew, who was in US Army counterintelligence, when a form of secret communication became standardized, it was no longer secure and thus, obsolete. The simple reason for this was, for something to become a standard, everybody involved had to know about it and the simple math is, the more people that know a secret, the more likely it is to get out. His team of 8 had a private method of talking that they told no one else, not even their commander, and they updated it on a regular basis. No, he didn't tell me what method(s) they used.
