The Spy Kids 3D: Game Over official website was created to promote the Miramax Films release, directed by Robert Rodriguez. To appeal to the film's largely young audience, the entire flash site was designed to be a game with five levels. The game interface also was a reflection of the plot of the film. Users can register as an OSS Agent, customise their avatar, explore the site and play games. The Spy Kids site also features the Screen Machine, a customisable wallpaper interface wherein the user can create and save their own wallpaper designs.
