Worked well on Safari. But this was funny:

"Chrome Frame Minimal effort for bringing IE6, 7 and 8 up to the latest HTML5 technologies"

I loaded it up in IE8 and chose not to use the chrome frame. The presentation returned a javascript error and nothing at all to read. Just a blank page now in IE 8.

This stuff is awesome, but what sucks is I fear that it's going to be way too hard to convince people to install something called a chrome frame to view the stuff they want. Although it was once that way with Flash, so maybe history will repeat.
