I'm not aware of any style of teaching/learning that is actually seen as 'cool' and not sure it should be. This is about using technology in a new way to achieve something. You can't force someone to learn - there still needs to be a desire to listen and be taught for any method to have an impact.
A number of University courses are starting to provide podcasts to support/enchance the learning and I doubt they're doing it for the gimick factor.
How would you like to learn?
