Effective UI has an interesting Flash UI for presenting menus on their home page using a stacked accordion. Upon landing on the home page, a series of stacked boxes are displayed with both a large descriptive heading of that section and shows the first mini-slide in that deck/stack to help you see what that section is about. Mousing over the first slide in the stack expands the stack to show the headings for the other nodes of content within it, and the user may now hover over the other items to view their descriptions. Clicking a card displays its content in an floated layer.

2. Mousing over a stack to expose all of the headings.
