Logo Design Plagiarism is a research project by Tom Appleton. It questions the importance of true originality in commercial graphic design, and the stigma around logos that look similar to another.
This research project approaches the issue from the moral standpoint of a graphic designer, disregarding what may or may not be considered correct in the eyes of the law.
How important is originality? It's a question with no one single answer. But it is an important question for designers and creators to be aware of, and to consider for themselves.
