From the website:
Welcome to the Accessible NCAA Tournament Bracket. This site is an experiment in making March Madness more accessible to the full spectrum of college hoops fans, including those using non-visual interfaces such as screen readers and those who are physically unable to use a mouse.
The main feature of this site is the bracket. It's an accessible bracket because it uses well-structured, standards-based markup that makes it easy for non-visual users to navigate and understand the relationships between games.
