Definitely, Minimalism. When there is so much noise around technology, the one thing that fascinates me is its silence! I am amazed by technology when it serves a purpose while being almost invisible. One silly thing that caught my attention was asking for a taxi at the hotel or office reception in Dusseldorf – the person invariably and almost immediately answers: “It’s coming”. How did she ask for it so quickly? How does she know the taxi is really coming? How will I know if it’s my taxi or that other guy’s taxi? But it always worked perfectly! I was so curious that I had to peek in – every reception counter had a single-button thingamajig to call a taxi. I was left to wonder how could I apply that simplicity in what we deliver.
