So a Blurp could be defined as a) a circle and a Blurp b) a circle c) a Blurp and a Blurp
And when rendering a Blurp it picks one of a,b, or c randomly (with weighted probabilities)
That single addition opens up a huge world of variety.
I'm glad I continued watching up to the point where the presenter puts symbols within themselves because that part blew my mind! I'd really love to see a feature like this incorporated into Inkscape and/or Kitra.
