Painting With Coffee
"Andy and Angel have been painting with coffee for several years, and have completed hundreds of original artworks. Curious people who view the work are amazed that the artwork is painted entirely in coffee - no additives, just 100% pure coffee."
They have a gallery of coffee-themed paintings, but they really do paint everything with coffee: portraits, wildlife, flowers, scenes from trips to Scandinavia. [via Tastespotting]
