SVG path syntax [1] mentioned as being an inspiration in the article is very similar to Turtle graphics (move, lineto, etc.)

Very many vector graphics standards use the idea of a current position. A distinguishing feature of turtle graphics is to have a current direction as well.

It's a shame SVG doesn't. Many shapes can be specified much more concisely.
