As most of you might know, Frutiger Aero is the aesthetic that used to be common on soap bottles, and windows. In my attempts to make it in Minecraft, I've found that Frutiger Aero, and it's substyles, are best handled by figuring out how to separate the Frutiger elements and Aero elements.
Frutiger elements are rounded shapes, human oriented design prioritising ease of use over style, and also generally the shaped smooth design. Aero elements include the iconic fish and dolphin details, even tho' those also lean towards Frutiger Eco. They also include stylized choices.
