Here's a funny thing I read about in last weekend's paper: wantsforsale.com. A couple of artists started selling paintings to make money for things they want to buy. From their website:
Each painting shows one thing we want, and sells for the price of the real item. So you can buy "A Slice of Pepperoni" for $3.00 or "Dinner at Nobu" for $152.00. When the painting sells, we use the money to go out and buy that thing.
This one's called "A Little Shopping in SoHo" and costs $2,500.00:
You can see the paintings they've already sold in their Flickr gallery.
Don't you wish you'd thought of this first? I do!
