Probably you all realized that designs in every part of our life are getting rounder and rounder everyday. For example old cars had sharp edges, old furnitures were flat and had sharp edges, most of all websites had more flat design. But today's cars has very smooth edges, furnitures have curvy surfaces and smooth edges, all corners on websites are rounded and other rounded elements..
I'm wondering is this just a trend or is it easier to produce these today? or does it have something to do with psychology? I want to hear your opions.
