Well i dont ever remember a pattern similar. i am sure it may have popped up but, the way the "Qtip" pattern is, it almost seems off center or something. it is real interesting. it should be a nice project for you to try and see what comes from it. good luck and congrats again.
also the request still stands to see some other patterns like that. it would be nice to see a thread dedicated to some of the more aberrant patterns other than just some of the usual variations we see within a certain trait.
