Music of note: Video games for those with visual impairments

With a musically inclined teenager in the house we have been looking at video games such as Rock Band and Guitar Hero. A colleague recently sent me a link to a story highlighting a college professor at the University of Nevada efforts to "modify already-existing games, to show that any game can be rendered accessible". His recent projects have been with Guitar Hero for the Wii. Check out the story at http://blog.wired.com/games/2008/06/gamelife-the--2.html
