Jeez guys, cut them some slack. It's a nice demo that happens to use a lot of features that aren't widely available yet.
The various browser vendors are never all going to sync their release schedules for new features. Now that we have some healthy browser competition and healthy forward movement on specs we can have either a) lowest common denominator sites or b) some sites that only serve a subset of browsers and either fail or fallback to less impressive tech.
Are we going to do this thing where we complain about every tech demo if it's not fully supported by all 4 or 5 major browsers? Sounds boring. When browsers come out with new features, I want to see demos showing what is possible. If you want to see it work on browser X then write a version that works on browser X and show us.
Every time I see CSS3/HTML5 demos like this, I think "awesome, but what's the IE situation?". I mean that in a honest way, not in a "oh, that probably will never work on IE type of way".
IE9 is supposedly way better than before - will it support stuff like this?
IE introduced expression() in CSS decades ago. Like -webkit-transform, they are both private non-standard way of doing animations. IE4/5/6 even had hardware accelerated 3D graphic and dynamic music support, dHTML was cool before HTML5 coolkids took over.
