The video opens up a line of conversation between its viewers by asking questions, but not answering them. "Are you a 'glass-half-full' or a 'glass-half-empty' person?" (01:16) Ultimately, the way the viewer chooses to interpret the subject matter tells more about themselves than it does about the creator of the video, and I believe that this effect is intentional. What better way is there to prove this than by looking at the name of the artists themselves. Everynone. A portmanteau of the words "everyone" and "none", the name further supports this idea of looking to yourself for answers, as opposed to the creator. In a very "Death of The Author" by Roland Barthes manner, the author's opinion needs not be considered in order for you to interpret the art. It is put together both by everyone and also by no one at all.
