Dig this: A camera device that records everything you’re looking at and hearing, via a camera attached to your glasses. Then, if you need to remember or revisit something recent — i.e. to recall precisely what someone said to you, or maybe just to find where the heck you put your keys — you can scroll back over the last four hours of your life. Or, it’d be great for those arguments you have with your partner where you can’t agree over precisely how someone said something. Endless fun!

The only downside is that you’d look like a dork of immense proportions with that camera on your glasses.
