It's been my experience that good design is more of an inner intuition than something picked up from the outside environment. That may be why everyone seems to be on the same page. Like those monkeys that began to wash their food in Australia, then another group started to do the same in Asia. One theory is that when we sleep, we all download our thoughts to a universal storage bank. I'm not sure if they have theories like that in Switzerland, but it is an interesting idea!
