Pips and Nubs

Some human technologies are so ancient and ubiquitous that we don't notice them at all anymore. Yet they are still so useful that we should appreciate the minds (whoever they were) that came up with them. YouTuber Craighill explains some of these design details and how they are found everywhere. The first are pips, which are concave dots. The second are nubs, which are convex dots. These two things are more useful than you ever realized, and they make life easier in so many ways. Then there's the basic mechanics of putting the two together. Pips and nubs combine properties to fill a lot of different needs. It's where we got what we know as the familiar "click." You'll know it when you see it in action. (via kottke)
