Over on the DVXuser forums I came across a cool post from user rlrydeen. He has crafted an "arm" made from PVC pipe that rides directly between his tripod head and legs that holds his 7" HD monitor. Not only does it work as a monitor stand, but when swung around the screen also serves as a teleprompter when fed by a computer. Nice!
You'll need to register to see all the photos, but it's worth it. There is a wealth of knowledge over at DVXuser. It's one of the best video camera forums on the web.
