In english: Start with
iteration, retrace that geometry backwards, but oriented 90 degrees about its
original end point. To show the curve you need to pick some arbitrary
number of iterations.
Any
-start+123 works just fine though of course the orientation and
coordinates will be different.)
For a more colorful display, with a different color for the geometry
introduced at each iteration, replace that last line of code with:
([:pd[:<"1|:)every'reset';|.'show';step&.>^:(i.
