Every sound he hears causes a taste to fire in his mouth. Even the barks of his dogs have specific flavors and textures.

To better explain his condition he mapped out the entire London Underground with stations and their corresponding flavors. See the full map.

Wannerton's map was published in The Best American Infographics 2014.
