The name behind the work of this iconic piece of art (the one you have above) is called "Yellow", by none other than Nathan Sawaya. When I was in Seattle (we also went to Vancouver, Canada as well) over the summer with family, I got to see an exhibition at the Pacific Science Center Museum? (Here is the meme:
