One of my favorite design tricks comes from the simple Kleenex box. Nobody even seems to notice that it's "broken" on purpose.
The box works perfectly so that when you pull out a tissue the next one is pulled into place. Every sheet you pull sets the next one up without fail. It always works until it doesn't.
About two thirds of the way down the box there is one single sheet that does not overlap the next one. When you pull that one "broken" sheet out the next one stays buried deep within the box. You have to dig it out.
Invariably it reminds us that the box is almost empty and that we'll need to buy more. It also ruins the slot where the Kleenex comes out and makes us desire a newer "better" box
Did you know that this is on purpose? Genius!
When I was growing up we used to watch the movie Wizard of Oz together as a family. In one scene, way back in the forest background, there is a crew member that accidentally makes his way onto film. He's not supposed to be in the movie.
Every year we would watch for this moment and try to "catch" this flaw in the film. We would pay close attention and then take delight if we were among those who saw the fleeting moment while others would moan that they missed it.
I've always remembered how this flaw used to catch our attention. I've used it ever since.
Sometimes I'll leave a "flaw" in something I've designed on purpose. People will "catch" the flaw and then like to point it out to other people. It gets their attention, "Oh, yeah, I see that!"".
It's just a way to stick in people's minds.
Tesla's are fast. VERY fast! And their designers are very clever.
There is a setting in Tesla cars that they have named "ludicrous mode". It is a software setting that puts the car into the fastest possible mode for the car. Naming the feature "ludicrous mode" wasn't good enough. They also added the following screen that requires the user to confirm their choice.
