After visiting the Guggenheim website's page on the Gutai exhibition, I came upon this piece by Sadamasa Motonaga called Work. I think it's beautiful. The caption explained that he was inspired by children's artwork and how they see the world in a pure and simplified way. I thought the way he handled color and how he filled the picture plane were equally beautiful and unique.

I also enjoyed Gutai Card Box (Gutai Art Association, 1962). I thought it was a beautiful way to expose how society is so used to things being automated.
