The internet seems to have spawned a whole movement of entrepreneurial artists that have worked out that an idea and a little viral marketing can get you a lot of attention and maybe even a little money.
I have already mentioned the Money series paintings, 1000 Paintings (and an imitator), Bond Paintings and NYC Rubbish. I think they’re probably all better ideas than they are art, but they’re all very interesting ideas.
Another idea is to paint something that you want (for example, one million dollars) and then sell the painting for the price of that object. One million dollars would be quite expensive as it would cost one million dollars, but if you only wanted things like a pizza slice ($3), dinner at a Japanese restaurant ($152), or a piece of steak ($18), you might find a buyer.
Christine and Justin from New York City are the artists (or should I call them entrepreneurs?) behind the project. Wants for Sale has a list of things that they want, while Needs for Sale has a list of things that charities need (with all the money going to the chosen charity.)
