It's either a joke or a gross misunderstanding of Brutalism. I mean, it uses JQuery, for crying out loud. That's not a slight against JQuery, per se, just saying that "Brutalism" would imply a use of raw materials in construction. To extend the metaphor, using JQuery would be like using wood over the bare concrete of a building to make things "better" for the user.

This is just plain bad. I think it is a great idea. It is a shame it's so badly done.
