Poppy 3D iPhone Camera ($39) should look familiar. Just by popping your device into the slot on top, you can shoot and view 3D images and video using your iPhone or iPod Touch. You can then share your videos or images on the web, letting your friends view them using their own Poppy, a 3D monitor, or red and blue glasses. While it’ll work using any photo or video app, they’ve also made their own iOS app to make things easier.
