I never said it is not a cool exercise. I meant more like it is not something one would download and compile and run it... like it is not a useful tool. Just a cool one. And that is fine.
Very few things on Hacker News are such that you can directly download and install them; I don't know why you'd have that expectation. Anything from a full app to a code snippet to a cool article that has nothing to do with tech is welcome here.
