The mythical napkin
The other day, during lunch, I was scribbling a few thoughts and ideas on a napkin. That got me some smiles and ironic comments on “the mythical napkin”. Somebody even asked if I wanted to borrow a sheet of paper.
But heck, no! The reason why I didn’t want to switch to paper was the real value of the napkin: The constraints it puts on the user. You have a very small patch to write down your thoughts or to illustrate that idea to your colleague.
You can expand by unfolding, but the essence lies on one small, 15x15cm sheet. Priceless.
