Valve invited a bunch of 7th graders from The Evergreen School to Valve HQ and had them all sit at computers and make Portal levels! HOW AWESOME IS THAT?! Basically, they had free-reign with the development kit behind the game, splitting them into groups of three and essentially saying, “Go nuts, kids!”
