Looking for simple Ethash script hashing real block+nonce as demo for educational paper

Looking for simple Ethash script hashing real block+nonce as demo for educational paper.
This will help other new potential miners and Ethereum investigators.
I'm looking for something like this...

http://ethereum.stackexchange.com/questions/2310/how-to-use-the-hashimoto-light-algorithm-in-pyethash

That thread is complaining of errors and also I don't think they used a real block from the
blockchain history.

I think this would remove some of the mystique of mining and dispel notion
of newbies that mining is black magic.

Thanks!

Chris
