Photographer Reuben Krabbe, whom you may remember from the landscape bicycle portraits hack, had his flash pull an untethered bungee jump during a session in the mountains. So Reuben came up with a great idea to balance a lightstand on uneven terrains. That figures with all those mountain bicycle trips.
Being the nice chap that he is, Reuben put a video together to explain how it works. Video and some thoughts after the jump.
