If you have children at home you could just point a webcam at their gameroom, or, depending on how obsessive compulsive their guardians are regarding cleanliness, anywhere in their homes. Of course, they won't be there all the time, and their guardians will sometimes cleanup, which means that such a generator will tend to be biased, which means you need an entropy extractor and entropy pool (but you knew you needed those anyways). Even so, I believe that such an entropy generator will generally produce better entropy than a geiger counter, at least when it's operational. I wouldn't put it past any PTO, especially the USPTO, to issue a patent on gathering entropy from a webcam pointed at tiny, human entropy generators. But IANAL.
