Microsoft's research lab is tooling around with a prototype of a digital camera you wear around your neck and which snaps up to 2,000 photos thoughout the day. It can even react to bright lights or sudden movements, or take more shots when your heart rate increases by guessing that something you might want to record is going on. Hopefully they're working on some software that'll help you make sense of all the thousands of photos you'll be collecting — otherwise having so much a massive visual record of your life will be pretty much worthless.
