There really is no end to the inventive uses of caffeine and its related delivery devices. We won't even get into some of the freakier experiments starring caffeine, and instead we'll focus on its artistic elements: Beautiful paintings crafted solely with espresso! Caffeinated Creations is the artistic brainchild of Karen, who was inspired to create the warm, rich pieces while drinking and serving up espresso in cafes from New Orleans to Tulsa. Described as a slow and detailed process, we loved the meditative and Zen-like description of how she works to build up the different hues slowly, layering espresso to create depth and texture. You can purchase her one-of-a-kind pieces, but if that's too rich for your blood, you can pick up postcards or prints of many of them as well.
