The main idea is symbolize the bronchi of a lung. The asymmetric design used in the icon gives to it an organic feel. I tried to keep it as simple and serious as possible, using single lines and common colors to the medical area. Hope you like it. =D
Not so different from the other, this one shows different colors, but still trying to transmit a clean/hygienic feel. The main difference is that this icon is more symmetric than the other one, changing the sensation from organic to technological. Hope you like it (too). =D
