I had seen a rig basically like this for video camera stabilization, this is a intersting idea that could really be expanded upon with a little creative thinking huh.......mmmmmmm maybe take a clay impression of the botton 1 inch of the camera, to make a form fitted mold, pour the lead, then coat it with the rubber tool handle dip stuff in the color of the camera. Then it'd be a bit less likely to scratch anything. It would then look like a verticle grip, or extended battery pack. Could even put a long brass nut in the bottom to put it on the tripod too. Well now that this idea is in my head it will stay there all day.
