The Stereo Chord EGG was a novel little circuit introduced in kit form by PAiA in 1976 as an interesting application of a then-new top octave generator chip. This kit hasn't been produced in decades, and commands a premium when one does turn up. Because I recently had an application for this random "music" generator, I decided to redesign it from scratch, reusing as much of the existing design as possible, but staying away from proprietary parts.
