Synesthesia is otherwise known as the neurological disorder characterized by a crossing of the senses. Often, a person with synesthesia will hear smells, or see sounds, and sometimes words have textures and tastes. It's basically my favorite neurological disorder, which sounds awful when I write it that way. I guess my point is that I'm completely fascinated by synesthesia and synesthetes. Interesting then, to read about Guitarati in WIRED magazine. You've got to check this site out for yourself, because this concept is just too cool to try to explain in words without texture or taste.
