Gadget Ogling: CES EditionRoader's Time Machine Camera is designed to hang around your neck and, for up to seven hours of battery life, constantly capture what it sees. When you hit a button, it saves the last 10 seconds of footage and the following 10. You can send a low-resolution version of that 20-second clip to your smartphone immediately, and if you'd like to save a high-resolution version, you can grab that too.
