The idea is simple: A taut cable between trees and a camcorder moving along and recording incredible footage. This is not 'Helmetcam' anymore, but it's 'experience', isn't?
Bri, has manufactured that homemade system for his Canon Vixia HF11, and he has edited the next video combining tripod, cablecam and helmetcam shots.

Perhaps the cable can be placed higher for next experiences, to make more spectacular compositions. Many sequences in this one looks made with helmetcam or similar.
The original pictures by Bri may be watched here. beside other interesting systems like chest-cam.
