I figured out that I'm kind of a fan of Austin Kleon's book, and I particularly like this assignment that we are supposed to post "artwork" that people at might understand better once they hear the story--the story of what it's about and why you made what you did.
I think that art, in all its various forms, is exactly this--subliminal messaging of your own thoughts and emotions that you are attempting to convey to your audience.
But I agree with Kleon's point--"Work doesn't speak for itself" and that "Pictures can say whatever we want them to say" (94).
Does this make you think of the Mona Lisa?
It's the most famous painting of all time, but honestly nobody really knows what's going on there.
