A free Second Edition IDL Programming Techniques book 
to the first person who can find the simple word I
embedded in this binary sequence:

0 1 1 0 1 0 0 0 0 0 0 0 0 0 1 1 0 0 1 
0 0 0 0 0 0 0 0 0 0 0 1 1 0 0 1 0 0 0 
0 0 0 0 0 0 0 0 1 1 1 0 1 1 0 0 0 0 0 
0 0 0 0 0 1 1 0 1 0 0 1 0 0 0 0 0 0 0 
0 0 1 1 0 0 1 0 0 1 0 1 0 0 0 1 0 1 1
0 0 0 0 1 0 0 0 1 1 0 1 1 0 0 0 0 1 0

Cheers,
