Joby's Gorillapod is a tripod designed for smaller, lightweight cameras that allows placement in a variety of places that traditional tripods just can't manage. The tripod allows you to utilize the environment around you with the three flexible legs that can wrap around a variety of objects.
Each of the grippy joints on the legs are able to bend and rotate 360 degrees. The base joints also have larger grips so the tripod can stand in the traditional manner without any slippage. It uses the traditional 1/4-inch screw and only weighs 1.5 ounces. Available for $25 through the Gorillapod website.
