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
