Squares and Triangles vs. Circles

Even if you break those 90 degrees up in halves and make them triangles…
it still feels less “kind” and harmonious, than circles and curves,
don’t you think?
Maybe it’s just me, but I tend to sense that surfaces and structures have “personalities” or “attitudes”,  and whoever came up with them must have been in a certain mood to come up with exactly this…
This is also the reason why I am Cei and not Kei
