The Museum of UnNatural Mystery offers a fine collecion of virtual exhibits nearly all worthy of mention but this one caught my eye. It seems that in Bucks County, Pa, there exists debris field of rocks, many of which "ring" musically when struck with a mallet. Listen to the short audio clips at the end of the article which demonstrate the range of these talented stones. Might be worth a trip to gather some audio samples eh, what? Could make an interesting mix for the VJ/DJ crowd. Look here for the stone exhibit and then follow the link box at the bottom to the main entrance and enjoy the rest of the "stuff". There is something for everyone!
