The Holland Festival provides a program browser/calendar that provides an AJAX interface for viewing over 3 weeks of events in a grid. Drop down menus are provided to narrow or expand by genre, locale and route. A single toggle highlights featured events. And a sliding selector, which can be dragged to move the range left and right and with handles to narrow or expand the window, allows you to filter the days to be shown in the grid. Hovering over the individual events in the grid provides a link to show the details in a dialog layer.
