There was a really cool video that had three creators of a product called  
 life lapse.. If I understand it correctly it’s aim is to capture  life on the go from a first person perspective…. they explained it to be like the data from  twitter but with a video… when i first saw the video i thought of lots of possibilities…. 

found the video under:  wsj for  all things digital
