The Buddha Machine is a hardware loop player, built kind of like a little AM radio, a small device for producing ambient sounds.
My son, 12 years old, made a small flash presentation of this device just for fun
[Intrigued by this succinct summary, I went digging and found some oddly lyrical reviews of the Buddha Machine. Its nine variants of "soothing" electronic ambient sound--perhaps better described as ambient music--fade from one to the next. A line output allows connection to a stereo system. Supposedly Brian Eno bought eight of them. --CP]
