HN is a nice example. Imagine if you let a designer loose on it, the disaster that would ensue. It would be eye candy for sure, but we'd all be leaving in a hurry.
Especially for stuff that is used frequently less design is usually better, 'b(l)ing' is for kids with too much money to spend on their cars. Tools have to be functional first.
They can aesthetically pleasing, but only if the form follows from the function they have. Once you can't remove stuff any more the design is optimal.
