Looking at the dragon curve Rosetta Code task, it seems that it is much prettier to draw the curve as an iterated function system over the complex plane:
load'plot' f1=.*&(-:1j1) f2=.[: -. *&(-:1j_1) plot ,(f1,:f2)^:13 ]0 with the functions stolen from Wikipedia. Could we include this as well? The example I gave is missing a plot option to not include lines between points (ie. just show points). It seems that I have used this before, but I can't find it now. Any hints?
