This is an old photographers trick - here is my design. Sometimes referred to as a string tripod or string bipod or string monopod. Also known as a chain tripod, bipod, etc... This device is used to stabilize a camera in order to get clearer pictures at a slow shutter speed. With more and more digital cameras coming out with vibration reduction or image stabilization systems, the string tripod has a new life.
Since image stabilization systems work best with rotational vibration, translational vibration can still create blurry pictures. By restraining the up-down left-right and back-front axis, you can lessen this vibration. Since with this design you still have rotational freedom, you can pan and follow something such as a bird or sports player. You can also recompose your shot with little trouble. Of course this technique also works well with non image stabilization systems.

Advantages:
-Cheap
-Easy to make
-No special tools needed (or really any at all)
-Hard to break
-Small
-You can use this where tripods are disallowed (such as museums)
-If the "tripod" gets dirty you can throw it in the wash
-If you misplace it, you can make another
-Rotational movement still available for panning and recomposition
Disadvantages:
-Does not hold as steady as a real tripod
-You can get some looks while using it

The parts you will need are as follows:
1x 1/4 -20 Stainless steel eye hook or eyebolt. 2 inches long or shorter.
1x 1/4 -20 Nut (May come with the eye hook)
40ft Braided nylon and/or poly cord (Parachute cord is recommended)
Optional:
1x Carabiner
All of these can be found at your local hardware store and should be had for about $5 total.

Also, consider using a taut line hitch on the eyebolt knot. This type of knot can easily be slid up and down the standing part of the line, but grips tightly when let go. This would allow the user to make a fixed loop for one's foot and perform a quick one-handed adjustment of the knot below the camera just before the shot, then hold the camera with both hands while shooting. The only problem might be that the taut line hitch tends to fall apart when it's not under tension, but once one learns to tie it, it can be recreated in a few seconds. If that's a serious issue for those who are challenged by knot tying, the taut line hitch could be replaced with a mechanical line tensioner, such as shown in another Instructable, http://www.instructables.com/id/Simple-Line-Tensioners-for-Camping-and-Backpacking/

"Who has a tripod?"
"I do!"
*brings out string tripod*
"WHAT IS THAT?!?!"
"A tripod?"
Unfortunately, I couldn't tell any difference between using a single leg, two legs, and no string tripod. I was shooting an image of distant small brances to really test the effect.
In practice, even with two feet anchoring a loop of string, you still have four degrees of freedom (camera body forward/back), plus free rotation about the pivot point at the eye bolt.
In addition to that, if the rope has any elasticity, you have to deal with spring effect as well.
This trick sounds great, but I couldn't tell any difference whatsoever.
