Yesterday, the air was filled with wanton speculation about potential uses for the Wii Balance Board that will be packaged with Wii Fit. Now we're looking to get all those ideas down in one place -- specifically, here. We've heard some things already, like surfing, snowboarding, and skateboarding sims, and maybe for boxing games, but what else can you think of? Feel free to be both outrageous and creative. Also, are you interested in trying out something like surfing with an interface like this?
