Wasn't there something about how 'high' sarcasm is undistinguishable from the real thing.

Unfortunately I can't make the distinction, and I think it's most likely the commenter was serious

Its actually a super fun excercise to do. I did that years ago with a browser game that showed images on login, some years ago. Also with python. It was a fun learning experience because it's so much more visual then your typical "todo list tutorial" or "hello world".

That's a really clever way of detecting the swirl effect. As for simply measuring overall sharpness, that could be thwarted by normalizing the FFT after swirling. That wouldn't help against the sum-of-edges technique though (in fact, it would make it worse).
