I strapped my helmet camera on for a couple of runs of gates on Friday. I didn't spend too much time fiddling with the camera as I wanted to work on technique and that was difficult with my rucksack on with the camera in it. The results aren't too bad though; I should either have looked up more (likely) or adjusted the camera to point slightly higher...

No doubt the file requires that you have all the latest Microsoft stuff for it to work, but what the hell, all the people that are likely to be interested should be able to view it.
