Great link, sent to me quite some time ago (last year maybe?) by my start-up guru colleague Jeffrey Priebe, probably in relation to a project we were talking about at the time. I filed it in my bookmarks and then it got buried.
Finally found it, read it (again), and thoroughly enjoyed it (again).
While the article outlines the experience of grad students creating computer games, it really is a brilliant model for innovation in a business, as well. I have seen start-ups (as well as business initiatives like new brands and new products) started this way.
