I took a class on modern art this past semester and we started with abstract expressionism, and I just missed cubism by a decade (the class covered art from 45 and on). I did learn about cubism though because a lot of abstract expressionists were influenced by cubism. I never fully understood it, but now I kinda wish I took the pre-req to this class D: Cubism is really interesting, imo. I never knew that the multiple view-points were supposed to convey time.
