Visualising large sets of information, such as complex schedules, is a challenging task. When given this task for, e.g., a web site, the easy way out would be to create tables and indexes and some kind of navigation system like a menu to access the data. This approach would lead to a web page that would quickly bore the user and would finding what you need an annoying job. Not so with the example shown here, which is a very clever way of giving an overview of the World Championship's schedule of matches. Without a single click, the user can navigate the schedule and get instant information while keeping a very clear overview. A great and innovative interface.
