The ultra thin geometry aesthetic is (in my opinion) one of the biggest aesthetics of 2020. The goal is to meld straight geometric lines with natural curvy lines to create amazing shapes. They are meant to mix an ethereal feeling with a feeling of stability. It’s like observing what happens when you make metal into smoke.
This kind of aesthetic is best achieved digitally, which I think is amazing for a year like 2020 where we have access to both computer generated and hand generated lines. This kind of aesthetic is seen mostly in tech design but I have also seen it used to create beautiful artwork for concert posters.
