Preface
The origin of Claude (cloud) is a typical in air on G string. The statement of clouds in the sky can be illustrated as above clouds (like the one from wallpaper), but also Claude is an existence “within the clouds”. For people who have experience in swimming, it is a sense of both flying and swimming in the clouds. 
The connection of sky and sea is a unit topic in many works. One of the famous is Three Worlds by Escher. It does interpret a connection not only as imagination or elevated description, but a true association that sky is reflecting on the sea. Although the work itself includes trees and things around a lake or pool. Another one is the traditional flying dragon. I am affected by this to create flying fish, but flying cat bus has been an icon in Ghibli Studio Totoro. The concept infinite is seen as from the description of sky and sea as a borderless but also a link to mind insight, to describe the vision large is often same as mind large. The language itself is not explicitly seen but the topic of “infinite” becomes an introduction to the three world.
Going back to Claude, it is introduced in Hamlet as a main character Claudius. It is seen as from an author’s viewpoint but not very evident. However, when taking a plane, the clouds from the cabinet window do look similar as sea. This viewpoint also connects well and offer an illustration.
