Towers of Hanoi in Flash

I was having difficulty turning my Towers of Hanoi game into a Google Gadget, presumably because it uses absolute positionining, and IE wasn't displaying it properly (actually it was blank in IE). So I've converted it to Flash, made some minor improvements, and I'm using someone else's Tooltip class (http://www.neo-archaic.net) to make the nice tooltips show up when you click the button.
