I'm glad you made this post. It seems you understand what I missed. The
    adding of two sequences. It's not that clear in the statment,

draw_line(colors[k],{cen[k],cen[k]+p2xy(r,rt/1800*PI)}).

After studying it I see it. It's so simple now.

I read some of Rob's old posts you put up a link to. Although a lot of it is 
above my head I get the gist. I know this was well covered in David Gay's
tutorial, but it has been about four years since I read it.
