Autographer

Wouldn't it be great if you had a photographer following you around, documenting key moments in your life without ever noticing he/she was there? The Autographer ($450) is designed to do something similar. Meant to be worn, it features a host of sensors — a GPS, accelerometer, thermometer, and motion detector among them — that work together to decide when it's time to take a picture. 8GB of internal storage ensures that you won't be needing to offload your 5 megapixel memories too often, but just because you don't need to doesn't mean you won't — it's got built-in Bluetooth so you can check out your shots instantly, no wires required.
