I’m quite intrigued by the products from Kyouei. An LED balloon lamp, a DVD that produces colored lighting for your home… Check out the description for the CD they call “Random”:
This CD used on random play mode only. It has 99 scales included in the 99 tracks. When using the “random” function, the CD will automatically select random tones, and make a new melody. And when selecting random and return function simultaneously, the new melody will play endless.
