Behold: Hatcams, baseball caps with standard camera-mounting fixtures on the bill. (I'll give you a second to stop chuckling.) But seriously, this could just be the beginning. For now, it's silly - cameras are too big and conspicuous, and god help you if you want to start and stop recording. But cameras keep getting smaller, and batteries and memory will last longer, so I can certainly imagine a sleek and socially-acceptable camera built into clothing - and always recording. It's similar to lifecasting, but more for the purpose of catching memorable life moments before they're over - and without interfering with your ability to experience them. Aside from that, imagine the value of having a video record of any altercation, car crash, or crime... Privacy may be the victim, but the possibilities are mind-boggling!
