This demonstration works in Firefox 3.5 and up, Webkit-based browsers (except for MathML), and Opera 10.5 Alpha. This is an XHTML document and therefore doesn't work in IE. To see the east asian Ruby annotations, you'll need the XHTML Ruby support extensions. If you wonder about the layout, check the building where the demo was done.
