Satarii Star is a robot head for your mobile phone camera

Satarii Star Accessory -- IndieGoGo

Our idea is the Star Accessory, a product that makes your mobile camera follow your every move. You can video yourself doing anything without the awkwardness of asking friends or complicated setups. It is a sensor enabled motorized base that moves your mobile camera to follow you and keep you within the image frame. And it gets rid of the need for tripods in a sleekly designed, pocket-able form factor.

Hands down one of the coolest ad-ons I've seen for consumer video. Count me in.
