Sure, clip-on PVRs aren't exactly revolutionary, but the vast majority of 'em require you to don some pretty fugly headgear. The VIEVU PVR-PRO, however, can be placed most anywhere on your person, so long as you're satisfied with the angle at which it records. This little bugger isn't much larger than a traditional pager (remember those?) and can reportedly capture video at 640 x 480 (30 frames-per-second), and while we're not told how much internal capacity is housed, it can store some four hours of content before needing to be emptied. As expected, the rechargeable battery also provides around four hours of usage, and it's not scared to get thrown around / wet either. 'Course, this gem wasn't designed for the casual lifeblogger, as the vanilla model will run you some $500 while the "encrypted police version" goes for two bills more.
