Brutalism is a style of architecture that lasted from the 1950s-1970s, and it was characterized by simple, block-like, hulking concrete structures. It originated in England and spread to the rest of the world shortly after.
I love brutalism; I am a brutalist and for this reason I tried to animate these buildings.
