I have been amusing myself with this little tool/app that accompanies the release of Alain de Botton’s latest book, Art as Therapy. They have created a website where you can click on a particular feeling or mood, and it will take you to a work of art which they deem has something to say to your condition. It might be a long bow that's drawn in some cases, but it's fun.
So far I particularly like this one, for when you are feeling fragile, and this one, for when you long for others to take the time to truly understand, and this one, for defensiveness. Go play. (Note, if you click that right arrow more will come up - eventually!)
