Synesthesia is a rare neurological condition that leads stimulation in one sensory pathway to trigger an experience in another. Basically, a short-circuiting in the brain that enables such strange phenomena like perceiving letters and numbers as inherently colored (color-graphemic synesthesia) or hearing sounds in response to visual motion. More than 60 types of synesthesia have been identified, with one of the most common being the cross-sensory experience of color and sound - "hearing" color or "seeing" music. These neurological eccentricities, however, can often be a source of tremendous artistic inspiration.
