Summary

Description
English: The Blancmange curve is a fractal curve defined by an infinite series. This specific plot adds only the first twelve terms in that series, which produces a result that is indistinguishable (by eye) from the true curve. This file was created using my own Python code.

The following Python code produces the y-coordinates used:

   import numpy as np
   def blanc_iter(arr):
       bumplength = 1/(arr.size-1)
       means = (arr[1:]+arr[:-1])/2
       newheights = means + bumplength
       out = np.empty(arr.size+newheights.size)
       out[::2] = arr
       out[1::2] = newheights
       return out
   def blanc_gen():
       blanc = np.array([0,0])
       while True:
           yield blanc
           blanc = blanc_iter(blanc)
