 | If you want "nothing up my sleeve" numbers start with a source that 
 | has long been published and do a simple repeatable manipulation to it.  
 | For around 2^14 bits, I think you could take a long novel (say, the 
 | Gutenberg Press copy of Fyodor Dostoyevsky's book _The Idiot_).
 | Separate it into sentences. 
 | Eliminate any duplicates.
 | Take all combinations of two sentences in a deterministic sequence. 
 | Produce a SHA256 block for each. 
 | Then publish the code that munged the book into the bitblock, 
 | publish the exact version of the book you used, and everybody can 
 | verify that the bits you used are in fact derived from that book 
 | in a straightforward way and that you didn't manipulate the text 
 | to get any particularly-desired results. 

Would you like to borrow my (first edition) copy of RAND's
_One Million Random Digits_, buy your own reprint ($60 USD),
or tell me what it is that I am missing here?
