We may not have seen it at E3, but it looks like David Perry is finally ready to show off his game streaming service, Gaikai, to the public. In a new video posted on his own website, Perry demonstrates how Gaikai handles, running games like Spore, World of Warcraft, and an emulated Mario Kart 64 on a standard computer with a home cable connection.

Those who want to give the Gaikai service a go can sign up for the closed beta test at www.gaikai.com. You can also find more info on the tech demo and the service itself at the source link.
