recursively change values in list of lists

I see no recursion in the problem as stated.  Can a polygon contain
another polygon?

I can see that if you had ...

  e_1 = [(0,0),(3,0)]
  e_2 = [(3,0),(2,3)]
  e_3 = [(2,3),(0,0)]
  triangle_1 = [e_1,e_2,e_3]

  w_1 = [triangle_1,]

... you might want to make a copy of triangle_1 that was offset by
some amount and add it to w_1. Is that the idea?
