The creative use of the iPhone is, I find, stunning. Every day I receive press releases for apps that I just wouldn't expect. Two new apps that illustrate this are Retina and Eye Glasses. Retina ($.99) is for those who are color blind. You simply point the camera at something, such as an item of clothing in a store, and the app will show the item in the camera's preview mode and tell what color it is. Eye Glasses ($2.99) lets you use your iPhone to see tiny text or other hard-to-see details. It uses the autofocus capability of the iPhone 3GS camera to clearly display what it is you're trying to see, letting you enlarge 2X, 4X, 6X, or 8X. Point the camera at something, and you'll see it magnified on the screen as the camera sharpens the image.
