(I guess this would go here. *shrugs* )

Has anyone else here ever heard of "synesthesia", specifically in the form of sound?

"Synesthesia is a condition in which the real information of one sense is accompanied by a perception in another sense. A person may see colors when hearing a sound or may experience a smell when seeing a certain color. Such a person is called a synesthete. There is much to be learned about this phenomenon."

I first heard about it from this Last.fm group, found it interesting, and then started researching it.

Anyone else here have it? Think they have it? Anyone think it's nonsense?
