I met a man the other day who told me he plays the vibraphone. I didn't want to appear ignorant so I just "Oh, how nice" ... What is it? Also, have any of you seen a harmonaphone ... it's a series of glass 'tubes' on a lathe like contraption which is turned by a foot treddle and you play it by dipping you fingers in water and placing them on the rim of the glass as it turns ... very cool.LL
