Briefly, I suspect you could use <ul><li></li></ul> for the list. Then make
each <li> clickable, and set the list node style via dynamic CSS.
A Google of [ul style css image] returns this:
<UL STYLE="list-style-image: url(green_bullet.gif)">
Prototype pokes styles like this $("wiki_panel").setStyle({"width":"50%"})
So just whomp in a spinning GIF, and you are done.
BTW making the dot itself spin ... is a good idea. Thanks!
