"If one geek's trash is another geek's treasure, start sending all those CD jewel cases you've been tossing to New York City, care of digital media artist Tristan Perich. Perich is the man behind One Bit Music, a project that uses simple electronics to turn clear, plastic CD cases into personal, lo-fi music players." Check it out here. And do visit Perich's site. He has some placed some scores and mp3 files of his music on his homepage. You will find it here.
