Here we go! Dave Perry's released a long video of his Cloud gaming app Gaikai in action, showing World of Warcraft, EVE Online, Mario Kart 64, Spore and others playing in a normal Firefox browser with apparently no plug-ins or downloads necessary.
Watch it after the break, and stay with it right to the end. Perry opens up Photoshop saying he didn't have to spend "$700".
The developer's going to be speaking about Gaikai at Develop in Brighton next month. We'll be there!
