What is the message? I think the creator wanted to tell us that logos are surrounding us and is everywhere.
What do they want to convey? I think logos are what we imagine how a certain company is like. For example, in the video Ronald MacDonald, from MacDonald is portrayed as a phyopathic killer clown and the michelin man is portrayed as a detective or a police. This means making a logo without thinking about your companies characteristics may lead to a misunderstanding of people looking at it.
