import numpy as np

def make_oblique(words):
     n = max(2*len(word) for word in words) + len(words)
     canvas = np.zeros((n, n), dtype='S1')
     canvas[...] = ' ' # ye mighty FORTRAN, we beseech thee

     for j, word in enumerate(words):
         i = np.arange(len(word))
         canvas[i+j, 2*i] = list(word)

     canvas[:,-1] = '\n'
     return canvas.tostring().rstrip()
