You can turn the mode on and off on the fly. I'm told that if you happen to have a pair of red and blue 3D glasses lying around the house and you put them on to watch this video it will look 3Dish. Of course I recorded this with a little handheld camera, so it doesn't really do the effect justice. But maybe you can get a taste of 3D guinea pig.

in Toy Story Mania, gamers play a number of mini-games on the Wii using the remote. Among the 40 mini games are ones that have you throwing darts to pop balloons, throwing balls to knock things over and throwing hoops over object for points. While the 3D graphics weren't on display tonight, the producers said that some of the games wold include the option to play in true 3D.

G-Force, a game based on the upcoming 3D movie, did have the 3D display on show this evening. Both the Playstation 3 and Xbox 360 versions of the game will support 3D graphics, which can be switched on and off on the fly.

The 3D graphics used in the game requires gamers to sport a pair of cardboard blue and red lensed glasses and uses a type 3D known as off-axis, the developers said. The effects seen in motion were surprisingly good, The guinea pig lead stood out on the screen, enemy shots seemed to blow out of the television and the world felt more realistic, though with slightly muddled colors because of the graphics.

Though not the first game, by a long shot, to sport 3D graphics the game certainly seems to put a shine on the red/blue technology.

The G-Force action title is set to hit on July 21, a few days before the Jerry Bruckheimer-Disney CGI live action film of the same name scurries onto screens.

In both the game and the movie, the story follows a team of guinea pigs who have secret lives as spies trying to prevent a billionaire drunk on power and money, trying to take over the world by turning household appliances into killer robots. You know, that old chestnut.

Despite the, to put it kindly, fanciful concept, the action game looks like it could be a relatively pleasing title for younger gamers. In it, players control Darwin, a guinea pig packing an array of neat gizmos. He has thermal vision for solving puzzles and fighting in the dark, an electric whip for melee attacks, a jet pack for flying and turning his four-on-the floor waddle into a sprint. He also can purchase eight weapons including guns that freeze, act like shotguns, rifles and even a gun that lets him hack into evil appliances and get them to attack one another. Darwin can also climb pipes.

While the game is based on the movie and it's appliance army, their are about 80 percent more enemies in the game than in the movie, said Disney Interactive Studios Ben Weitz.

The game's 30 or so enemies include walking irons that shoot fireballs, flying CPU coolers, weaponized toasters, alarm clocks, waffle makers and electric shavers.

Darawin also has a device that can weaponize appliances, instantly turning them into enemies, but also letting him use them to solve puzzles, like using their attack to blow open a door or get him around barriers.

Finally, Darwin can call on the help of a house fly named Mooch. Mooch has to stay within a certain distance of Darwin and can only be used for a set time before returning to the guinea pig, but he's got some specific talents useful for puzzle solving.

He doesn't die, he can use a laser to throw switches, he can fly and he can temporarily slow down time.

All said the game, which is being developed for the PC, Playstation 3, Playstation 2, Wii and Xbox 360, will run about eight to ten hours long. Separate DS and PSP versions are being developed by Keen.

Weitz said that the studio is also looking at releasing a free and paid version of the game for the iPhone. Something more along the lines of the iPhone based on Bolt and meant to work hand-in-hand with the marketing campaign for the movie.

While the movie features the voice work of Nicholas Cage, Tracy Morgan and Penélope Cruz, there's no word yet on who may do work for the game.
