Nintendo DS Sending Signals to TVs?

Thanks to Slashdot for pointing out this mysterious story. It seems that some DS users have been reporting fuzzy images of their games appearing on their TVs. There is a logical explanation of course, from one forum user, "I think that this is the result of the videocable to the top screen is just a little too powerfull. It's also possible to "tap" the video signal from a VGA cable, they both emit very faint signals of what's going through it." It doesn't seem it's intentional, but it's still cool.
