HW: How to ruin a good design

In the article, how to ruin a good design, the author describes how good designs have ruined. In London, once well designed signs were ruined by a new design that mad them hard to read, which shouldn't happen with road signs. Another ruined design were chairs that McDonalds commissioned that mocked the original design, making the original look bad. The article goes on to how companies have ruined their own recognizable logos, to lackluster designs. In my opinion, changes to recognizable designs should only be made to make it better, not to ruin them.
