The Go Pro has a head mounting which works like a night light/miners lamp. It fits comfortably over your head, with the box on your forehead and not on top like a square unicorn.
My only comment on the Go Pro is that the various physical mounts were susceptible to vibrations, which was annoying. Putting it in time lapse mode solved that, and quite frankly was a little more useful than lots of video. Though that is more a matter of personal preference.
