Have you looked at your windshield wipers lately?
I love little "niches" like these. So many things in our lives are so filled with "depth" that even extremely observant people will never notice.Sometimes I just sit back and wonder at what the designers or manufacturers of common things had to deal with.Perhaps the shape of a mug handle was a point of contention between several people, or the thickness of your desk was the result of a compromise that came from a grueling 4 hour long meeting, or there is an engineer somewhere that is extremely proud of the weeks they spent designing an office chair wheel that won't suck up a cord, or the designer which worked several weekends in a row to completely redesign the shape of the base of a desk lamp so that the regulatory sticker could be placed on the back and not on the front.It makes me feel better when I feel like I'm wasting time trying out different button shapes and sizes for a stupid menu somewhere deep in an app that nobody will ever really care about.
