Foster goes on to say that while they were teaching an art class together on the north shore of Oahu in 1970, Robert Landry began one class quoting Albert Einstein, "Imagination is more important than knowledge, for knowledge limits us to all we know and understand, while imagination embraces the entire world and all there ever will be to know and understand."
Then he sketched out a scene, and told his students that he wasn't going to paint the scene as it existed, but rather how he imagined it would be on a rainy day.
To the left is the painting he produced that day, a rainy Hawaiian day. The students told Robert no one uses umbrellas in Hawaii. Robert retorted, "Now they do."
