What a terrible article.

I think my favorite example of their ridiculousness is the "eye movie posters". Yeah, eyes look like eyes. And yet each of those posters is still distinct and, further, is extremely different from most other movie posters!

The only things that they've discovered here:

* When you get hundreds of thousands of instances of Thing, it's easy to find some that will be very similar.

* Some kinds of Things have functional reasons to look very similar - like skylines (there are only so many ways to build a skyscraper!)
