The right cable is a mini-stereo to mini-stereo cable. EDIT: Leroy's response below is better; I had a brain-freeze.
If one has a Creative (What U Hear) or Realtek (Stereo Mix) sound card then one does not even need a cable. Couple a cable/no-cable setup with Audacity and you're set.
I think it's an "easy" way to anonymously/cheaply post fan fiction and get attention/subscribers. Because starting a blog and/or getting a fanfiction.net account isn't easy enough, or easy enough for the intended audience to find. Maybe.
