Zack Rusin’s demo from aKademy 2005 at Malaga is here.
The link is about “xgl”, but I’m almost sure that Zack presented Exa, not xgl there. And if so than this is what we will have in X.org 7.0/6.9 – quite soon! And yes, that’s what will be used in KDE 4. Finally we have our response for Gnome’s demo from last year 🙂
Beside of that… Guess what browser Zack uses there… humm… is this… Firefox? 🙂
