20,000x
We've now magnified our view 20,000 times, and the big round shape to the right is the head of our previous fractal flea. Like the 60-foot-tall farmer who finds Gulliver when he's marooned in the Land of Brobdingnag—we can't forget Swift, can we?—the larger flea dwarfs yet another, even tinier flea clinging to its long "mouthparts." (Run with us here a bit.)
