Here's a neat invention that looks good. Beep Industries wants you to make their iPhone 4 camera button/grip a reality. The Red Pop will use the base of the iPhone 4 and uses a 30 pin connector to connect the shutter control. You'll be able to get a good grip, plus there's a button that you can use to snap pictures, like a real camera.

Let's hope they get around to doing it. [Kickstarter via Gadget Lab]
