How does it work?
I heard some people talking about it. But what is the explanation for this to work?
A sensor bar is nothing more than a source of light spots. Candles are light spots
I wouldn't say that as a light bulb could then be called a "light spot"
In fact, you could even use two light bulbs. However, you may have to put a piece of paper with a small hole in it in front of each one, as otherwise the 'light spots' would be too huge for the Wiimote to track precisely.
