I happened across this site: http://www.dunehaven.com/1-line.htm which discusses single point KAP suspension ideas. The wind vane rig was appealing but I didn't have any time to go to the hardware store. After rummaging through some cabinets I found some thick milkshake straws. I decided to improvise and build a rig for my 808 key fob camera that is light enough to be flown on my 18 inch tall TALA kite anemometer kite.
I cut one straw down the middle (lengthwise) and then folded (lengthwise) it so it doesn't curl back. I then simply taped it to the back of the first straw and rubber banded the camera to it. I then made a 2 leg bridle and attached it by slip-knot to the CG and the back of the "vane". This will then be suspended from another short length which attaches to the flying line.
Regardless of how its made I do believe these wind vane rigs are really intriguing and I recommend every KAPper to give it a try.
