We did catch someone saying "this makes the Wii look stupid." And, actually, it kind of does. The 3DV Z Cam is  a minuscule video camera equipped with an infrared beam, roughly the size of a web-cam, that sits on the bottom of your TV. That's where the fun starts. Flash gang signs to change channels or flick various components on or off; have a virtual dance-off outside of a specific square; KO a cartoon boxer with real jabs.
