I was a bit bored last night and made a cool but useless JavaScript. Try moving your mouse over the menu to the left and see for your self. For a peek at how it’s done look at the script (MouseOver HighLight) itself. On my machine it hogs a great deal of CPU time but only when it animates. It requires CSS and a bit of DHTML i guess. But it’s not that without it the page get unreadable.
