In this tutorial video, Griffin designs a $14 third-person body-mounted camera rig out of PVC pipe for his GoPro Hero2 camera, to capture unique over-the-shoulder shots.

ADDITIONAL BUILD INSTRUCTIONS (I'm using " to mean inches.)

Using 1/2" PVC pipe (it's bigger than that, but that's what it's called), cut the following 13 lengths of pipe:
-(6) 1.25" pieces (These are to connect fittings together. When inserted, the two fittings will cover the entire piece.)
-(2) 8.25" pieces for the tall, vertical sides of the rectangle
-(2) 2" pieces for the short, horizontal sides of the rectangle
-(1) 12.25" piece for the long camera support arm
-(1) 5.75" piece for the short camera support arm
-(1) 4.5" piece for the camera support column

(Now that I'm adding these up, I'm realizing it's about 73" of PVC—that's 6 feet and one inch. I used two 5-foot pieces of PVC, because of lots of trial and error as I figured out the design, but this is interesting: I have more than 5 feet remaining. They must be longer than they say.)

You could also substitute each pair of T joints and 45-degree elbows with a single Y joint, but they can be hard to find in stores (since plumbers have little use for them).
