Comics are a great information design medium for sequential visual/verbal information.  If you're mostly used to verbal instructions you might think that all information is sequential, but it's not.  A lot of information is best explained spatially.  Emotional Freedom Technique, also known as EFT or Meridian Tapping, is both.  Actually, it's spacial and kinesthetic and verbal and sequential.  Comics works really well for this whole combination of information types.
