Top view of the Micronium chip, which sports six tiny mass-spring systems. The colors are caused by an optical effect: the rectangle representing the mass has tiny holes in it, causing reflection of light.
It's much, much smaller than its Stradivarian cousin, but not even the Borrowers, Lilliputians or Blefuscudians are of sufficiently diminutive proportions to take a bow to the Micronium. The tiny instrument is made up of microscopic springs activated by combs to produce an audible tone. Half a dozen tone systems are placed on a chip and then chips combined to offer an orchestral range of sounds.
