A link posted by a newbie to a github rep that only has executables, and no source? That's a pass from me...
It also has controversial statement.
Is this theft?
If the found address is 5-12 years old without movement, it is a lost coin.

What about "my private key is generated from 111th block's hash in bitcoin blockchain"? You do not remember exact value which is used to produce private key, but you remember the way how to find it - exactly like "my phrase is second verse of song X".
One thing is sure in my opinion - brain wallets belongs to past.
I'd argue it's still brainwallet since in practice brainwallet accept any/arbitrary input which hashed using certain algorithm. Besides, it's still practical to watch over ~748K address (based on ~748K block hash) using bloom filter.
