Stabilising camera mount design.

After my rather disappointing results trying to get aerial footage from my kite I've designed a mount for the camera. I know I could have Googled a design but for me half the fun is in the design and prototype stages of the project.

I decided against gyroscopic stabilisation, the cost of the three powered precision gyroscopes alone killed that idea pretty quick.
I then remembered an episode of scrapheap challenge from years ago where they had to carry open barrels of paint on a vehicle trying to spill as little as possible and that inspired my design. My idea is for a mass damped stabiliser that should be as simple and quick to construct as possible, no gimbals to make and make use of existing materials.
