Hmm, this YouTube video has me wondering if Nintendo ever thought of this, of course, this is fairly dangerous to do. You have two candles in front of the television. You have the Wii with the sensor bar unplugged, and you have the Wiimote and Numchuk, and then you have an RPG of sorts. Somehow something as old fashioned as a candle can prove to be a wireless sensor bar, something that baffles me beyond recognition. I'm no scientist, but this seems like something that involves light waves. Could be wrong.
