I found a set of cheap plastic racquets at Toys R Us and ordered a remote camera shutter button for about seven bucks on Amazon.com. As luck would have it, I was able to simply stretch the elastic webbing of the racquet over the corners of my iPad2 to attach it. This holds the iPad firmly and securely against the plastic frame so you can hold it in any direction.
The camera button is attached to the hand grip with double-stick tape and its cord plugs into the iPad headphone jack. The completed rig lets me hold the iPad with one hand and use my thumb to click the shutter. I can also flip it over so the button is underneath and use my "trigger" finger. This is way easier than holding an iPad with two hands and pressing the buttons. It also lets me hold the iPad up higher to take photos above a crowd.
NOTE: This works perfectly for taking photos, but for recording video... not so much. Because the shutter button plugs into the headphone jack, it disables the microphone. This means it will start and stop the video camera but you will not be recording audio. A work-around for you Spielberg-wannabes would be to have a separate audio recorder and add your sound track later.
