Hi, Chuck!

Not for glory...
But in the sake of interest.

to fract.curve.for_Chuck
for [:i 4 1 -1][setpc :i fract.curve :i 150 180 pu home pd]

to fract.curve :st :r :dl
 if :st=0 [arc2 :dl :r  stop]
 fract.curve :st-1 :r :dl/3  lt 60
 fract.curve :st-1 :r :dl/3  rt 120-:dl/3
 fract.curve :st-1 :r :dl/3  lt 60
 fract.curve :st-1 :r :dl/3
