a few months ago (in October 2009) I wrote a blog post about "The Fun Theory" and how games in applications can help to increase the satisfaction of the users while working with an application.
Today Office Labs (a creative, future-oriented, experimenting department of Microsoft) published "Ribbon Hero" - a concept prototype that should help users to learn Word and Excel. I want to share this with you because this is the first realization using game mechanics in "boring" daily-business applications.
Try it, and probably we can share our highscore in facebook :-).
PS: Hopefully my mum likes the game and I needn't explain the ribbon anymore.
