Pantone Pen Print
Daniel Eatock draws a blurred line between fine arts and design. His work Pantone Pen Print uses a whole set of pens lined by color value onto a stack of paper and left to bleed for one month. The experience produced 73 prints numbered from bottom to top and sold from £1 to £73. You can read the whole descripition of the project and see other great ones at designboom. A similar project, Balance Poster, does the same but upside down.
