Editor's note: Like many great love affairs, the Impressionist movement started in Paris. Like many great, revolutionary ideas, its creators were treated with cruelty and disdain by the established painters of the time. What a huge "told you so" the early Impressionist artists could enjoy now, if only they hadn't all died in abject poverty from never being able to sell their work. (Van Gogh sold one painting in his lifetime. One.) So let's show these brilliant artists some posthumous love by getting wallpapers of their work, shall we?
