You're all smiles today, little buddy. What's up? The Hololens. What's a "Hololens"? Goggles that project holograms and computer interfaces on top of everyday things. Next time I'm sitting on a crowded bus and someone's rump is right in front of me, I can turn it into a tv screen. Or play solitaire on it. I've been waiting for this tech my whole life. Can I project smiles onto the grouchy?
