Saul Bolanos: Cafegrafia

Saul Bolanos from Costa Rica developed a photographic process using light sensative emulsion to transfer liquid coffee images onto tiles. Since then he has developed other forms of coffee printing including coffee art masterpieces on coffee filters.

It's incredible. "Coffee Images can also be produced on coffee filter paper. They have the Aroma, Color and Taste of Pure Coffee and are 90% Costa Rican Coffee with 10% humidity. There are no other ingredients. Each Coffee Filter Image is a work of art,
or just put it in your coffee maker and drink your coffee art." *taken from http://www.squidoo.com/coffeeprints
