That's my symbol grin emoticon My researchings Time and
   cognition a few years ago, I kept writing this > . < everywhere.
   Couldn't figure it why I kept doing it. Then when it clicked in
   I was like: DUH - the points of the > and < overlap each other
   slightly and are superimposed! I felt stupid in that moment
   'cause I kept them separate.   I was so proud of myself, I
   registered a website for a year called "stitchlock . com" made
   it into a fake fable, and then made a Vine describing it with
   music. I think the domain is gone now, but I still remember when
   the > . < overlapped and the dot was in the middle - it was a
   great "duh of course" moment. [1]https://vine.co/v/MKOiu2ajZjp
