Romain Guy has put together a very interesting Hands-Free Shooting Rig over at MacDevCenter: "Here's how to build a hands-free photography rig using an iSight, a Bluetooth headset, a backpack, and a dash of AppleScript that enables you to capture images on the go by simply speaking, 'Take shot.' Romain Guy shows you how to build it." How awesome is that? 12-inch Powerbook in a backpack with an iSight sticking out of the cellphone holder that starts taking pictures when you say, "Take shot" into your bluetooth headset.
I'm going to build the same setup, but instead of "Take shot," I'm going to have it take a shot every time I say, "That's hot."
