There is no doubt in my mind whatsoever that the future of art is in public exhibitions in which everyone can take part as no matter how old one is, he/she can participe in that art event. "Obliterarion Room" is a very original exhibition where people are given a sheet of Polka dots and are asked to place them wherever they prefer.
I haven't actually been to an art event as that one, but I'd love to! Have you ever been to a public art event?
