Today I read an article that claimed to distinguish the differences between art and design. I am not sure I agree with all of it, but cases can be argued on both sides. Here are the arguments the article presents:
Art is creating for the artist.
Art has no goal.
Art is exploration.
Art is interpretative.
Art creates problems.
Design is creating for the end user.
Design has specific goal.
Design is observation and iteration.
Design is unanimous.
Design solves problems.
