We usually write about products you can buy, but the iPhone4 Photography Kit is a concept that's on the drawing board, waiting for your support at Kickstarter.com. The kit is a slider case in three parts, plus an optional neckstrap. The left and right parts slide together and are sealed by a locking ring. The end result looks like a digital SLR with the ring resembling the camera lens. Actual photos are still taken with the iPhone 4's built-in camera. White and black are planned with potentially five additional colors if the project takes off.
