Who mentioned creating a card describing TN?

Hi folks, I can't recall who blogged about designing a small business card size describing TN. The deaf and hard of hearing community passes out small cards with the intent of educating folks. Did anyone actually design one? I am thinking this would be a great idea if someone doesn't have it already. I am so tired of trying to describe and having people look at me strangely. Yes, it sounds strange. I am in the health care and I never heard about it. Anyway if someone can respond to this I would really appreciate it why reinvent the wheel?
