Stare hard at this photo. Stare really hard. Can you guess what you’re looking at? No? Maybe because your eyes aren’t working hard enough? Maybe you should squint your eyes? OK. It’s your eyeballs. Your amazing, microscopically structured eyeballs. Squint harder!
Remember as a kid how a couple of googly eyeballs stuck to a rock could turn it into a pet? Well, this is the 21st century version: a pair of giant blinking eyes that can turn any gadget into a seemingly living companion.
